Adam and eve.

Its cuz of adam that we are sinners. How is it just then that we should get punished for sinning if adam was the cause of it consdiering that we are bscly destined to sin cuz of, again, adam. We inherited the sinful nature and then we have to get judged cuz we got born with this nature cuz of adam. I get that Christ disovles this entiery and grants a way out, but even if one rejects Christ, i struggle to see how it is that just to punish one for his sins if he was destined to sin cuz of the sin of adam. HELP me understnad this cuz it bothers me.
