Bad things happen to good people, and the reverse I suppose.
Who decrees what is a bad action and what is a good one?
Actually we have so little control over most of our lives and decisions. Although it's not something we like to acknowledge.
3/4 of the trajectory of our lives is set in motion before we even exist, where we are born, our gender, our parents, etc.
Who would choose to be born into a war torn or poverty stricken 3rd world country?
If we or an omnipotent being (such as Karma?) can't give us what we need to flourish in life, why should it pay back for the wrongs we do?
Ignore me I'm waffling
