Evil is NOT some Being that is easily recognizable by sight, such as myths that claimed the devil came with horns & calved feet. REALITY is that it lays within our unseen & unknown HEART to everyone else, even those whom are closest & just a breathe away.
The only evidence for Humans to know what or who is evil is thru COMMUNICATIONS & ACTIONS TAKEN - what one says & do, OVER time to know a person. Most mainstream religion have teachings that are UNADULTERATED by time, even if mis-interpretations by sincere BUT foolish & lacking in knowledge of the overall concepts for such teachings whose sole purpose is to elevate & progress Humanity.
Unfortunately, NO mortal is perfect & mistakes are the only way to learn & progress, but CRITICALLY to admit to it & correct it to progress. Most do, but some whom are indolent with selfish personal desires of lusts - power, greed, pride, etc, would rather everyone INNOCENT else follow their examples & perish together than to admit their mistakes....
May the foolish whom had been used & abused, wake up. Evil speaks with sweetness in attempts to fool one to believe it's sweet words that one wants to hear to validate one's unsupported evidences & REALILTIES that sadly are often harsh & bitter, but nevertheless REALITIES each Human will have to confront with courage in order to progress & evolve peacefully.
If one is foolish enough to believe evil & its darkness of doom & gloom by others, then, go ahead, support evil & dance with the devil. When the forces of Light appears,, the devil will run away, leaving the fool to face the light & consequences of accountability.
However, it is NOT the fool that the forces of Light are seeking after. It is the devil, to end its evil ways to Humanity....And in this metaphorically tale - the devil is Hamas for its Slaughter, Massacre of innocents & yet held NOT accountable & still holding hostages to be beheaded if its demands are not met....
