Agreed. It's not right to take something's life through pure fear or hatred, or so we can use them for ornaments, food, etc. Although, in similar cases to what Blizzard reminisced, if you kill something without meaning to, through shock, or even 'manslaughter', you can't be completely to blame.
Anyway, I sense we're starting to go offtopic now, from animal rights to the 'Is it right to kill?' argument. Back on topic people I think.
