Parents can sometimes say things out of frustration that hurt us, and sometimes are way off base.
I don't know your story but he may be trying to say things that hurt to make you look at your situation.........He may also just be a jerk
As far as the question of whether or not to have children b/c of the crime and pain in life............everyone has a different opinion on this.
I've looked at the things that have been hard in my life and thought- I would rather not have another person suffer that way. BUT then I think of the beauty of life, and I personally believe if a soul is going to be born, it is going to be brought into the world by me or someone else.......
I want to have children one day (maybe) b/c
to me, the darker times are lessons that everyone will have to face in order to grow.....and the good out weighs the bad.
Yeah, life can give you a shitty hand, but you play the game with the hand you've been dealt- You learn the lessons you need to learn, you can come out on top.
I think having a spiritual base (I'm not talking belonging to an organized religion) can help you find what your purpose is- and what life in general can offer you.
(At least, this has been the case for me)
I hope things look up for you and you find your path
