Here's a rule specifying a violation in basketball:
A Kicked Ball Violation occurs when a player intentionally kicks the Basketball.

And here's one from football:
A direct free kick is also awarded to the opposing team if a player commits anyof the following three offences:
......
• handles the ball deliberately (except for the goalkeeper within his own penalty area

In basketball, you can use your hands but kicking the ball is an offence. In football, you can kick the ball with your legs but using your hands is an offence. Why do you think this is? Shouldn't kicking the ball always be wrong? Or always right? Obviously, no.

The point is, right and wrong are decided by what you're trying to achieve. Raping and killing are definitely wrong, if you're living in a society where mutual cooperation and trust are very important. In war, killing your enemy is not wrong at all. In fact, medals are awarded to people who kill a lot of enemies. Any state that doesn't allow its soldiers to kill enemies is extremely unlikely to survive. Or if there is an alien invasion like ones we see in movies- killing is not wrong in that case.

Bottomline is, there are no absolute rights and wrongs, only actions that are better and worse for achieving some objective. If you want to live comfortably in a prosperous society at peace, then you need to observe these morals so that the citizens can trust each other. If you're at war, the right thing to do is to destroy the enemy.
