I was always against retribution and the death penalty but now,I don't know?

let me explain>>>throughout the years there have been serial killers,molesters,rapists that were caught.some got the death penalty some didn't.but I have realised that society most of the time ociates these monsters as being sick or insane to commit such attrocious acts.WELL WHY CAN'T WE SIMPLY ACCEPT THAT THESE MONSTERS ARE SIMPLY EVIL? If we can believe in good then why not evil? The greyhound beheading up in canada really blows my mind away!A man simply starts repeatedly stabbing a fellow penger who happens to be asleep and then beheads him and then taunts the police with the victims head and now more details are surfacing that the man continued to dismember his victim and resorting to cannibalism and was also collecting body part trophies!!!!!All this took place in a crowded bus and I can't figure out why no one intervened!!But then again,I wasn't there so I can only imagine the horror being witnessed by these pengers and the fear gripping there hearts at that moment and not believing what they are witnessing.Which brings me to my first question.I put myself in the parents shoes and I cried for them,Only God knows what they are going through as they continue to hear about there beloved son's last terrible moments of his unfairly short life at the hands of a demon.I call him a demon because no self respecting human being with an ounce of conciousness would commit such a heinous act towards another human being.And once again the media is putting more emphasis on the killer than the victim.There is no death penalty in Canada but I know now in my heart that I do wish that the killer was executed because I put myself in the parents shoes.Monsters who do harm to children and women should pay the ultimate price.I say this because there is evil out there and it has to stop somewhere down the line.Therefore I am changed and I believe in due process with the death penalty for these kinds of monsters.I would like to wish the family of TIM MCLEAN(the victim) my deepest and most heartfelt condolences for there terrible loss and that one day they can get through this and find peace in their hearts for I know in my heart that their son is with God and that Jesus waited for Tim and then took him to God.As for the killer,he may not want representaion nor he may not speak much and he told the judge to "please kill me";I guess he wants the easy way out.well I say this to him:We may never know what true darkness lurks in your soul or mind and I guess no one really wants to but there will come a time that you will have to explain yourself to one judge-GOD-,two witnesses-Jesus and Tim Mclean and NO lawyers and then you will truly know real judgement upon you....Please help me in expressing our deepest condolences the the victim's family and let us never forget of other victims of violent crimes>GOD bless us all and deliver us from evil.
