Why God, Why?

If anyone says they've never questioned God, they're lying. All of us has questioned God whenever stuff goes wrong in our lives. It's natural because many times, situations happen that are out of our control and we want to know why God would allow this. The Bible mentions that God reigns on the just & unjust. It's not fair that one person can mess it up for everyone but that's what I gather from God raining on the just and unjust. Reminds me of my school days where one kid did wrong and the whole class got punished. You can be faithful & obedient, live by the word and still have to face the same wrath as a sinner. I can truly understand why most non-Christians don't want to come to Christ because if they see Christians going through worse situations than them, what's the point? It's not wrong to question God as long as it's to find your calling or ask why some people have a good start in life and others have the odds stacked against them. When you see someone who had a good start in life whereas you had to fight for everything you got, you're going to ask God why did they have everything handed to them and you had to hustle for yours? Some people go through so much in life (out of their control) they end up turning their back on God. Why live for Christ and you go through more as a Christian than in the world? Now I would NEVER turn my back on Christ but I have wondered the rationale of living for God when you're predestined to go through hell? Those same people you used to run with before you got saved aren't checking for you anymore because you tightened up. At the same time, I realize God is not required to explain himself to anyone, myself included about why he does what he does.
