More b/s. Christian fundamentals do not teach that God's plan is to take everyone to heaven. Sounds like more Catholic crap. The original 'plan' implemented by God was to 'Be fruitful and become many and fill the earth and subdue it', nothing about dying and going to heaven.
In fact I once had a conversation with an ex-catholic who's daughter was killed being run over by a car. When his local priest tried to console him by telling him the usual nonsense of 'God wanted her as a flower in his garden', the man asked why God chose 'being hit by a car' as his method of taking her. The priest could not provide a sane answer to that and the man came to the conclusion the priest was full of shit and stopped being a Catholic.
Another stupid teaching, which has scarred the reputation of organized religion terribly.
Even though I am not Catholic I can somewhat understand what the priest was trying to accomplish. I think the priest was trying his best to comfort your friend. It is really difficult to know what to say to someone who is grieving like that. Often the best thing is to do is say nothing at all. Just being there is what is needed most of the time and it was foolish for the priest to respond like he did it sounds like.
That said, this world is filled with horrible things, death, sickness, abuse, etc. But we should be hopeful that there is a place where there is no more death, sickness, pain and suffering.
I know we would like to think that this place is for everyone regardless of their choices in this life, but that is not how God ordained it. We can argue with Him. We can fight Him. We can raise our fist at Him and tell Him how incredibly unfair it all seems. But how fair was it for Him to receive beatings and even being crucified on a cross in one of the most horrific deaths this world ever had just for our sins? That seems the most "unfair" thing of all to me and I am forever thankful for that.
It is all in our perception of things.
