Well, I'm not everybody's saviour. This is a call for everyone to put ideas on the table, not just me. I posit the 2nd Amendment vis a vis gun control as the issue to discuss. It is up for discussion.
Let's arrive at a solution, shall we? I doubt that the person who pulled the trigger regarded himself as soulless. Rather, I figure that he figured he was justified in what he did, by whatever justification (rationalization) he applied to thinking that his actions were a good idea at the time, twisted or not.
Up for examination is what is it about our laws that permits this sort of thing, repeatedly.
