Does God strip us of all emotion when we go to heaven?

Having a ‘discussion’ with a couple of conservative Christians on FB over the Paris Accord. They’re all in with Trump, of course.

One point I brought up,and am trying to stay focused on because they can’t deny it, is that all of our oil and gas reserves will be gone in about 100 years.
I said, “You need to look at your children, your grandchildren, great grand children and think about that.”
The response was, “Hey. I won’t be around to see it in 100 years so what do I care?”
I said, “Wait. You’re a Christian. You WILL be around to see it, won’t you? You’ll be in heaven looking down, ‘watching over’ your family, right?”
Of course, they have no answer to that.
To me, it was SO hypocritical. Isn’t that an atheistic stance?

So, then, that led me to this question: If you’re a Christian, in heaven, looking down, how will you feel when you witness the misery that will be our future generations because you didn’t do anything to protect them when you had the chance?

And that, of course, leads to a whole other ball game. What if you were horribly abusive to your kids your whole life, but got saved at the last minute, and realize what you’d done wrong, but by then it was too late? How do you feel looking down, seeing the misery that you caused, perpetuating itself through the generations?

Someone made a comment that there was a Bible verse somewhere that said for those in heaven looking down, there will be a lot of tears for those they’re watching who won’t make it to heaven.
I countered with, “But what if you’re the reason they won’t make it to heaven?”

I think it’s a good question, and I’m surprised that in all my years of questioning I hadn’t thought of it before now.
