I dont think anyone has the amount of power to say if a life should be taken or not. The person who injects them with poison or who turns on the electric chair or whatever, i dont find it justifying at all, just hippercritical, they are still human themselves. But then again they deserve everything that comes to them? Its a hard issue to debate, no one should ever have the authority to take someone's life, overall i think it would just be easier if people like that never existed.
