Bottom line: It is wrong to destroy one life for the benefit of another.
It is no more possible for people to see eye to eye on this than it is to discuss abortion. so why even discuss it. Some think to stop this is equivalent to stopping the splitting of the atom, the discovery of properties of matter, the exploration of space. Others see this as murder.
So why bring it up at all? All it leads to is the dissolution of any ability to discuss anything on this board which is about at the breaking point.
