When Adam was expelled from heaven, he was banished from a life of abundance to a life of deprivation, from living among fruit, green view, water and security to life of desert, of desolation, of survival and of danger.
It was (and still is) a tough and difficult process, a process that caused Adam to lose his soul, his goodness, which made him leave the innocent and positive place he was in and start hunting, killing, murdering and being afraid of being hunted, or being murdered or dying in any other dangerous way.
