I would agree that you need to manage your expectations here a bit. Life is not a morality tale a story or a bible verse. It is random malicious and unpredictable. Looking at the natural world where wild animals live exposed to the environment and predators at all times. There is no court of hunger/lust/chance. The expectation that societal rules and courts can somehow defeat the laws of nature to make it just or fair is unrealistic. Justice happens through our will alone and giving up on it voids your right to complain about it after the fact.
Buck-up speech well and good, I would strongly suggest you seek help. From this writing it is clear your emotions are clouding your judgement and it only gets worse from here.
