So much reason... But I have to wonder if my advices really will teach you anything. Well, here goes~

Fist, don't sacrifice others thoughtlessly.
Second, don't pretend to be a hero when your 'powers of justice' are based on taking everything from others and giving nothing of your own.
Third, make sure that everyone you slaughtered is really dead.

...Those points should be all pretty logical, shouldn't they?
