The things this man did are fucked up for sure but the things that led this person to commit such atrocities are probably just as bad if not worse.  I believe anyone is capable of committing the worst crime imaginable just as anyone is capable of performing the most selfless act. It all depends on a person`s up-bringing, experiences, genetics, etc.  Killing and locking these people up for life doesn`t solve any problems.  We should be studying and learning from them to prevent such things from ever happening again and helping them to try and solve their problems but we don`t do it because it`s easier to just get rid of them.  We need to get out of this old way of thinking.  We know better. We`re all capable of so much more.  There just needs to be more patience, sympathy, care, and compassion.
