Scenario: I'm a solo player, and I love to grief people. I run around in the wilderness and I see somebody collecting something/farming mobs/crafting/whatever. I get kind of close to this person and start a tribe, then proceed and attack that person and he can't fight back because it's my safe area. After I'm done, I disband the tribe and go look for next target. If this makes me go evil, then I will just use an alt and keep deleting him once he turns evil and give the loot to my main.

Scenario 2: "Good" griefers do this to "Evil" players w/out any penalty or risk.

Am I over thinking this?
