Kixie, it is not about morality of killing etc. it is about social security, if some
person has such instincts it is not a human, it is not even an animal, it is
very dangerous monster what should be removed from the society ASAP to
not poison it anymore. In nature everything ill and weak is removed, we
are human, we can take care about ill and weak members of our society
but we can\'t take care of such monsters, we can\'t feed them, give them
any priviledges and what is most important - we can\'t let them to be alive
or free. Punishment for such crime such be an example and warning for
other who even if has such instincts to never let them out.
Regards.
