Was there any punishment for killing someone (not patricide) in ancient rome?

If not killed outright, they were sent to prison to serve time. And if they were very unlucky, they'd be chosen to fight as a gladiator in the Colosseum for the rest of Rome's enjoyment.

Ipersonally feel that adolph hitler was a great contributor to american society. "to conquer a nation, you must first disarm it's citizens." sound familiar? hitlers research and studies have even made an impact on our medical research today. walt disney was actually a good friend of hitlers and in fact made an episode of mickey mouse in which donald duck was a nazi. as bias and judgmental as american society is they will never acknowledge the true impact he has had on history as well as society as a whole.
