This world is built on revenge. If you hit someone, they'll hit you back, and everyone knows it(yes even you Mastaq).
Karma, usually when people say love, they mean like, compassion, not hatred, what you said was towards hatred "love when class is over" that's not love, its more of hate.

you love shooting at people with a sniper gun
- but you hate getting captured by the cops
That is both hatred. Hatred is when you do something bad, though you love killing people, that is doing something bad.
