In season 2 when Aron Eisenberg and Chakotay are having a space battle,(Initiations) why can't Chakotay just leave the Kazon well enough alone and let him die? I think it's a poor strategy to keep people alive who are actively trying to kill you. But no. Chakotay has this ignorantly compassionate idealism that means you beam the enemy aboard your ship and keep him alive against his will. If he really wanted to have compassion he would have respected the Kazon culture and let him die if defeated. I bet that's what Picard would have done.
