It's nice sentiment to wish someone is at peace....
...but from every indication this man was under the influence of some potent, powerful drugs 24/7!....and quite frankly, I've never heard a religious sentiment or expression out of him....
What were his spiritual fruits?.....certainly not his predilection for little boys.
But you're right....we'll all stand before God.
All the more reason to pray for people--even strangers--who may be living a hell on earth. What changed me from being an agnostic to a Christian was the prayers, compassion and example of other Christians. If the Almighty inspired enough people to care enough to pray for me, then why shouldn't I do the same for others. Prayer can indeed work miracles, that's all I can say. So I pray for his family, if they had faith once, that they will have it again.
