Hi Raindrops hope that you are well! I am so sorry for your lost, I truly am . I think that I would have questioned if there was a god maybe that would be wrong of me but that is how I feel. So many good people are taken away one way or another and so many bad people are still on earth, I don't get it. But what I do believe is that the day will come when the person who done this to your son will be punished one way or another.I myself don't live by religion. I live by a relationship with God. Religion hurts people in many ways.
Eternity is a loooong time to not even consider it. Don't dwell on it but know that it does exist for everyone.
Everyone is allowed their opinion. I give my opinion by experience. My son was killed by someone 3 years ago. He will never know his children, we will never receive another hug from him on earth. I have forgiven this young man but he will never get caught. My son augured with someone at a gas station who had a knife. Personally, I would hope that if this person doesn't receive judgement on Earth then he will receive it in front of his maker. Eternity is a long time for someone, who doesn't ask for forgiveness.
To think that this man can turn his life to good after realizing what he did and then he'll go to Heaven... I would hope that this wouldn't happen because then all those who do strive to be good, it's a waste of time, because if someone who commits murder can just enter into heaven for changing their life around for the better, there's no justice in that.
