Sometimes, being a bad guy in our little movie called 'life' helps. You're constantly scared because you 're trying to be a good guy.
Is being the bad guy or getting your revenge utterly non-spiritual thing? If you go overboard you'll get your punishment of course, but no one is perfect. And life is more like experiment, it allows everyone to test their free will.
From time to time, be the bad guy. Yell at people who annoy you, snap at people who abuse you, stab somebody's back(NO, NOT LITERALLY) who betrayed you.
Just sometimes, not all the time. Monsters aren't afraid of darkness.
Of course keep moderation, because every action has consequence.
