Why good people suffer?

Last week I was asking myself a question. A question that has stayed with me since my childhood but rises to my conscience on certain occasions leaving me bewildered.
The question is –“Why good people suffer?”
And I know no one has a satisfying answer.
It’s both difficult and dangerous to be good. Being good gives us simplistic happiness, honesty of purpose etc. But it needs courage to remain good.
I have seen people who practice good going to jail, losing in relationship at workplace, money and health wise. Though not all of them, but many of the good suffer. So do many of the bad.
But the problem is both good and bad exist. And the fine things in life come to both of them irrespective of their purpose in life.
Picture this: A teenager like Ruchika who lost her mother as a kid was harassed by a senior police officer and saw her family being harassed for years. While the police officer who has got everything in life does this act and has woman, his wife, to protect him all the way.
How could one justify this situation? Nothing asking from the government or judiciary....asking God if such a situation exists. Then why?
Ruchika never had the option to enjoy life while this old man has lived his life to the fullest. Even if the case progresses against the alleged culprit and he’s convicted punished. How much harm will it do to him?

Ruchika’s story is just a case point there are many such instances where injustice is inflicted upon the good. And we have never found an answer why?
