10 Movie Heroes Forced To Kill For The Greater Good

10. Dr Manhattan Takes Out Rorschach - Watchmen

In Watchmen, Rorschach is pretty much the black sheep of the superhero ensemble: his methods are unconventional, his worldview cynical at best (and entirely nihilistic at worst) but he remained a self-appointed protector of men. Mostly in order to save them from themselves.

Right up until the finale, he was also the most grounded voice of reason - unseduced by the glamour of superheroism and not as disconnected as some of his fellow "Watchmen" - but once the reality of Adrian Veidt's plan for world peace through genocide, he flips on the rest of the heroes' moral compasses. He states his intention to uncover Veidt for what he is and threaten the fragile peace between the US and Russian built on their unified fear of Dr Manhatten and more genocide events.

And unfortunately for him, the only way to stop him - as he tells Dr Manhattan - is to kill him. He's an innocent, but he stands in the way of world peace, so Manhattan explodes him. All for the supposed Greater Good - though Rorschach's diaries will end up uncovering the truth anyway.
