Vigilantes

“	Vigilante: a crime prevention organization that operates outside of legal procedures. A vigilante group also refers to members of vigilante groups who encourage vigilantism.	„
	~ The definition of "vigilante" as seen after the intro in My Hero Academia - Vigilantes.

“	There's war in Gotham City. Perhaps where crime is concerned, there always has been. But seldom this open, this rabid. A madness seeping into every stratum of criminal society. Escalating like a plague, threating to surpass even the horror that created me.	„
	~ Batman

“	Vic: I swear I’ll tell them what I did. I'll turn myself in really. Cal: They'll just let you walk. Cause no one does sht to you. Vic: Okay fine, then I won't say anything at all. Cal: My dog will still be dead Vic. Vic: Please then what do you want? Cal*: To make sure you can never do it again. To make you pay.	„

Vigilantes are those who take the law into their own hands (many vigilantes in fiction wear masks and capes - hence the popular title "masked avenger"), they can be similar to anti-heroes and tend to work outside the law, as some of their methods includes murder or violence. However, no matter how good their intentions may be, all vigilantes are ultimately hypocrites as they are willing to dismiss civil and legal laws while punishing others for acting similarly (normally heroic vigilantes justify this by adopting a strict personal code to differ themselves from their enemies but some of the more extreme examples can be no better than the villains they fight against).

Some could even be Tragic much like with Batman from the DC Comics who happens to do the exact same thing but with a tragic motif with his parents and eventually for the sake of protecting those in Gotham.

By vigilantes' ignorance to the justice system, a vigilante could inevitably cause trouble during their actions and had a chance to made a grave mistake by end up killing a wrongfully convicted person and worse, take an innocent life as well. That is why many vigilantes cannot count for Pure Good. Due to Vigilantes taking matters into their own hands and possibly interfering with the law which makes them anti-heroic, their chances from fitting into Pure Good would be really difficult. However, it is not impossible for a vigilante to be pure good and they can end up qualifying if they have remorse, meet all the criteria and lack any corrupting qualities (e.g. Spider-Man, Rayman, Superman, Izuku Midoriya, Lloyd Garmadon, and Elastigirl).
