Eating people is another thing that's considered evil. However, one time there was a plain crash in a very deserted place. It took weeks for the rescue team to find them. When they finally found the group of survivors they noticed that the bodies of the people killed in the crash had been eaten by the survivors to stay alive. Is eating other people a bad thing at that moment? Should they've just starved to death, leaving their spouses, children and families behind? Good and bad are very difficult subject matters that change from time to time. Some people might think it's bad to say something that goes in against the majority. Others admire those people and think it's brave.
