I'm not making a case for the rapist, glad he's dead, one less fucktard to deal with. But what what it comes down to is i dont believe that you can be judge jury and executioner. I'm making a case for State Law and to a lesser extent, civilization.
People will see this verdict and think its OK to beat people to death in "X" circumstance. There is a reason that every law breaker, while scum bags and general shit stains on earth, is not sentenced to death.
