Karma to those who mock disabled?

I believe that "what goes around, comes around" in some way or form. I have a disability. All through school I was teased by this one group of kids. About 10 years after I graduated I ran in to some of them, one has a dead end job in the fast food business, another has a daughter with a disability, and the last ones was in a car accident and is paralyzed. I however do not hold a grudge, I help them out when I can. Whether it's a $10 loan, an offer to babysit or just sit and keep someone company. They have become good friends to me.

No. That's only wishful thinking.

I think mocking the disabled is an all too common form of human cruelty, not a massive sin. However, our actions, words, and thoughts create consequences for us to experience and learn from, and so, yes, there will be consequences (karma) for people who injure others

Of course not. It is a silly idea and even if it was possible why should it happen they would have already punished themselves by showing their stupidity

I do not believe in Karma. If God does not punish those who mock PWDs within their lifetimes, then God will punish them eternally in the afterlife. Eventually God will punish them within their lifetimes and/or in the afterlife. Sin is sin. No sin is greater or lesser than another sin.
