10 Comics Heroes Who Broke Their Mentor's Rules

When it comes to rules, Batman is the hero with the most concrete selection. Or rather, the most concrete one, as his 'no-kill' rule is perhaps one of the most well known things about him.

And so, when it's revealed that Jason Todd - Batman's former Robin, who was killed by the Joker and then made significantly less dead - has turned a new, pro-murder leaf, the Dark Knight is naturally devastated.

Todd breaking this rule under the new mantle of the Red Hood does make totally sense though. Given he literally died to a supervillain, it's only natural that when he's brought back, he's more than a little bitter about the fact that his murderer has essentially gotten off scot-free.

Though indiscriminately slaying anyone who looks vaguely shady isn't exactly a baller plan, you also can't totally fault Jason for changing his MO a little after the whole 'beaten to death by a crowbar' thing.
