Life sucks.  And there really is no way out of it. 

Sometimes, I really feel as if the idea of religion is just a way of some sort of exit for people...

Why do people have to made to suffer?  No matter what religion I'm talking about, even the ones with reincarnation.  With the talk of karma, I could understand that if I've done something to someone, naturally, something bad would be back on me.  HOWEVER, if I don't remember anything from the past lives as people who talk about karma love to talk about, why should I get punished? 

If a person did a crime, got amnesia, became a good person: should we still punish them?  Even when we're watching TV, we'll most likely say "No."  So why should a person have to get punished for things they don't remember?  If you really want them to learn, at least let them remember what they've done wrong so that they could learn from their faults.
