The Black Void

I really hate how there is no morality, no right and wrong, no better and worse here. Only what is makes YOU feel good. Well,
*Driving my car at excessive speeds makes me feel good.
*Not doing my homework
*Burning myself
*Defying authority
*Beating up arrogant and querulous bastards
*Walking around by myself at two in the morning
*Criticizing others
MAKES ME FEEL GOOD!

Sometimes, it seems that doing things that make you feel good aren't socially acceptable.

If learning new, interesting, or important things in and honest, in-depth, and unbiased manner makes me feel good too, does that mean they are probably detrimental to my physical and mental health as well?
