Why do people that does bad things get the most and better/finer things in life?

Because those people are not afraid to take what they want, even if it's at the cost of someone else!
You can believe in all that cr*p about suffering in this life, to be rewarded in some fairytale, pixiedust-filled afterlife... but that won't bring happiness in this life.
This is how the world works:
Those who aren't afraid to take what they want, while thinking mostly of their own interests & advantages, and not worry about who's toes they have to step on while taking it... are the ones who are rewarded with the Big-Shot lifestyle, you talk about.
