Fair Or Not Fair, Need help

Ok i run a shard, Now lemme say when people make me mad on it, i get... mad =p

so heres what happened, first A player comes on my shard and advertises a shard , and takes some of my players away! and he insults me and calles me all this crazy shit.... Anyway, i go find there sahrd and i GUESS! the admins password and tottly screw it over

Anyway, a bit later i changed my shard a bit, and some of the players left due to the changes, one of the players made his own shard copying alot of my ideas and went on my shard advertising, i knew this player well i talked to him before, anyway i found out and, i saw that his admin password was the same one he used to make an account on my shard, so i logged on and tottly wiped everything...

well, i kinda got rid of my compition but only cause they tempted me to do so... Was i too evil?
