Well I for one would like to know if the OP was asking if murder is worse than rape or if killing was worse than rape. because you can justify killing, but you can't justify murder. they are two different things.
If that is indeed what the OP meant, I would say murder is worse than rape, because of the already mentioned chance of recovery.
