God Always Gives You Free Will to Choose Your Path. The enemy of our souls instead chooses to take away your free will and impose his will on you either directly or through the works of others.
By harming others you remove from them their free will because you have chosen at that moment to put your free will and choices before theirs. They would not choose to be harmed or hurt by your actions against them but you took it upon yourself to impose your will upon them, taking theirs away.
You can always know the enemy by his works to remove from people their free will and choice in any aspect of their life. But be vigilant and clear on this point, the enemy is an expert in hiding this work of his through lies and deceit. The enemy will make you feel like you actually do have a choice by giving you multiple choices to choose from, then by this he can proclaim his innocence saying that he in fact did give you free will to choose. Free will is however not limited to only a few choices, free will is the ability to choose your own path free from the influences or limitations imposed by others.
