It's something the Poles and us Irish share. Repressed Catholic guilt. You're simply guilty by being born and God watches everything you do all the time, until you die and then he judges you on how you behaved while shouldering a monkey on your back.
Of course it would be a much better world if there was no God watching over us, life was meaningless and there was no justice when you died. Any of those who do evil in this lifetime will get away with it, and being a good person who are generous and lives an honest life, treating others with respect, well that's meaningless, at least in the long run, because we just live, die and who really cares.
That's the life I assume you believe in, but the more frightening and hard to understand thing is, why you think that things are actually better this way.
By the way I take it you live in Poland right? When in Rome buddy. Stop bashing Polish Christian tradition. Or perhaps go to live in Saudi Arabia and do the same there for a while. See how far it gets you.
