A basic principle of life is "You reap what you sow." Whatever you did in your past life, that is what you will gain in your present and future life.
If I sowed well and have a huge, wonderful garden, and I see my neighbor who didn't sow well and he and his family are starving-- what does it say about me if I look at him and say "You should have sown better", without giving him from my bounty? It means I am without compassion.
I'd rather hang out with the generous people who treat others "unfairly". Like Jesus.
