People fall into darkness and evil of freewill. When people don't deal with what causes them dysfunction it keeps them living the same cycles. It leads them down the rabbit hole of more agony and pain, which leads to darkness and evil. They end up chasing all of the wrong things, the wrong people, in the wrong ways, and for the wrong reasons. Until people get to the root cause of why they are the way they are and why they continue to cause self inflicted pain in their lives, they will continue to fall into darkness and evil. It leads to death of souls and destruction. If you don't love yourself you will always think the enemy is someone or something else; when the enemy is actually you/yourself! You'll remain your biggest threat and greatest enemy UNTIL you deal with what's causing you dysfunctional ways of thinking, feeling, and living. If you open the door to darkness it will spread like a fire.
