I thought you were smart enough to take "killing" as a starting point
Since I am bored at work, I'll take a minute and enlighten you:
We have GMs here on RO
We have cops IRL
When a character gets jailed, he can log on another char.
When you get jailed IRL, you stay until you root in jail, unless you are Chuck Norris. He can break iron like thin wood sticks, anyway..
When you get banned on RO, you come back when your ban is done OR use another account.
You don't get banned from real life? Unless you are dead maybe?
RO has rules
Life has gay laws enforced by power-hungry morons bending the law into their direction to make their life easy
In conclusion:
Getting punished here is nothing like getting punished IRL. Your friend "decided" break a rule, thus he gets his well-earned reward.
Get over it and just zip it (For the 50th time). Your arguing is getting nothing done
You think you're saving gorium? Well you're not
