Death Will Change Them
There are some that will prey on the kindness of others, and in turn make them suffer, until death. Few things you say or do can change that. There are others that can change in many important ways with our help. It is our responsibility to determine who is who, and to rid ourselves of those who seriously hurt the community.
As much as change happens during a lifetime, there are some people that will never change in the ways that we would like, until they are dead. There are some psychos that need to either be medicated in an institution, exiled with force, or dead. For the rest of us, party on!
So for all those that will not change their evil ways, and deliberately increase suffering on those that do not deserve it, only death will change them. But death will come to them, and they will die. They must die, because we all die, so we know that they will die. Death will change them.
