Thanks for stopping in, Chandan.

I'll let others speak for Judaism and Islam, but as for Christianity...there are explanations in the Bible for why "some suffer" and "some enjoy." The Bible tells us why there is pain and suffering in the world.

You of course may not agree with the Bible. You may not like what it says. And that's certainly your prerogative. But..whether you like the answers or not...

The answers are provided in the Bible.

All the Best!
