If a crime fighting vigilante like Spiderman or Batman existed, He should be stopped.

(Yes, I'm aware that they're fictional)
In the PS4 game, Into the Spiderverse, J. Jonah Jameson's podcast makes the argument that Spideman should receive police training and become a part of the official law enforcement if he really wants to stand for justice in New York.
And he's not wrong. In the game, Many people get hurt by Spiderman, Who isn't just harmlessly webbing it up. He swings heavy riot shields at the bad guys, Which could definitely result in bodily harm.

It says most of what I have to say.

Would we not want average people to be Good Samaritans? Want them to stop a harmful crime if they had the power? How much more then, When they have great power as Batman and Spiderman possess?

I'm not saying we wouldn't want them to call the cops, But time is not always available, Nor are the police always able to do what should be done. Not without being assigned paperwork until the end of their lives behind a desk.

Now to be fair, The title says stop them. I say this because Batman did join the Justice League. Spiderman in many iterations has joined the Avengers (I think). But, If they did not want to work for the government or an organization, Should they be forced to? This I think is more than can reasonably be expected. To expose themselves as even more targetable than they already are.

Take the Spiderman crazy journalist fan. Would it not be worse if she could target Peter Parker personally? His loved ones personally. You ask of them a decision, Sacrifice 'all of your normal life and the normal lives of your loved ones.

Should we not expect of any man to be a man unto themselves? Able to make their own decisions about what is right or wrong? Do more than robotically follow orders of a military or government?

Perhaps the supervillains would go away as they did in the Incredibles, But I do not think that they would in the DC or Marvel universes. (Not sure on that though)

Riot shield and back breaking can be explained away by video game physics. Never an actual danger. Like Looney Tunes.

I'm not sure what governments policy on crime lords is. Do they avoid arresting them because they are avoiding a power vacuum and lack the power to contain it, Or are they enmeshed in yellow tape and so weak as to even remove them in the first place quite often?

The questions were rhetorical, Though you can answer them if you feel you must, There were a lot.

I disagree. Many of those were not rhetorical from my perspective.
At no point did I say that they shouldn't do good things. But MatPat made a lot of good points.
And joining organizations like the Avengers and Justice League doesn't help in my opinion.
The Avengers are affiliated with the government through SHIELD, But until the Sokovia Accords, None took any responsibility for their actions.
I don't think the Justice League is tied to the government at all.

"Would it not be worse if she could target Peter Parker personally? " I never said to to reveal his identity, Just work more openly with the police, Rather than catching criminals and leaving them for the police. I imagine that filing a report after Spiderman helps save the days takes much longer.
And what about Tony Stark? He's very open about his identity, But Potts was never put in danger because of it. Sure, She was kidnapped by the "Mandarin" in Iron Man 3, But Killian already had a personal agenda against Tony, Not Iron Man.

There's no written policy on crime lords, But I believe the unspoken rule is don't create a power vacuum. As for being to weak to arrest him, It's a) difficult to prove his involvement in crime, And b) he likely has forms of blackmail against people like the district attorney and the mayor.

Not everyone wants to give up their rights and freedom to the government or society. Not everyone wants to be a celebrity. I don't think Parker has any 'good reason to believe he would only get good returns out of telling joining the police/military/government.

Nor does everyone want to become a celebrity like Stark.

How could he know that he would get humane treatment? Not be locked up, Treated as a monster, And so on?

I imagine for many people, If they could arrest crime lords, They would.

"Not everyone wants to give up their rights and freedom to the government or society. Not everyone wants to be a celebrity. "
Spiderman already IS a celebrity. He's also got increased public interest because of the masked identity. He would probably have a brief flair in popularity if his identity was made known, But being a high school/college age student isn't as glamorous as being a millionaire, And he would probably fade to the background, Especially in the MCU, With all the "gods" and Hulks and aliens running around. However, There is something to be said about having a normal life as well. So if you're saying that he doesn't want Peter Parker to become a celebrity, I can understand that.
I don't think he'd be giving up his rights and freedoms by joining the police force, Or some sort of special response team that is part of the government. And I think that he could arrange to still have a private persona, As long as his crimefighting alter ego is transparent with the public about his actions.
Inhumane treatment? If the police or government have any bad intentions, His spidey sense should warn him. Also, To include Batman, Who we've rather accidentally excluded from the discussion, Batman would probably not be treated inhumanely, As there is no basis for it. And in the Marvel or DC universe, The world is a lot more tolerant of people's "differences. " You can't guarantee that he would be treated inhumanely. As long as he negotiated the terms of his involvement with the government carefully, And made sure that it got in the news so that they couldn't just make him disappear.
While I agree that most people would take out a crime lord if they could, That doesn't make it the best choice. The best thing to do, Obviously, Is to prevent one from rising in the first place.

Eh, We come to the end. I'll reiterate my arguments and add a few in a fashion. Video game physics make it pretty easy to wail on some guy in a video game, Without them always being crippled for life or killed. Normal people get a bit more sympathy than crazies, Terrorists, And criminals.

In one of the comics, Spider Man comes across a movie set making a movie about him, But they refuse to sign the rights to him as Spider Man, Stating they need to know his secret identity.

The police likely would also have difficulty accepting anything but complete control, Authority, And knowledge of Spider Mans identity. And with the number of corrupt cops one could meet, Spider Mans identity could leak easily.

Super Heroes often have secret identities for reasons. To protect themselves and their ways of life, To protect their loved ones.

Spider Man 'has joined the Avengers in some iterations.

In many of the comics the government and private companies 'do seem to make it a point to lock up, Experiment upon, And target 'Supers. How much or little could be argued, But still I say it is there.
