Euthansia Controversy

This a complicated topic. I kind of don't even want to discuss it, because who are we to know that helping someone extremely ill commit suicide is wrong. Is a person in a vegetative state have to stay alive is it really necessary. Or is killing someone the right thing to do when the are technically not conscious of the world around them. The topic seems a little sensitive. I personally feel uncomfortable discussing it. The reason being because I have no idea is right or wrong, and I don't have an opinion because of that. This life is complicated enough who are we to decide or give our opinions on the matters of life and death.
