Satan hates humanity because God created man in his image. They’re described in the Bible as being a little lower than angels, however, and are easily corrupted. That is Satan’s chief weapon against us, and why humanity is fallen.
Satan also took 1/3 of the angels with him.
Humans can't resist that kind of power when that many angels couldn't even do it.
It requires Spirit provided supernatural strength.
It's amazing that anyone could be saved from such a powerful enemy and really begins to give insight in what a powerful weapon we have in prayer, which is far too neglected in this world.
I've even been guilty of it and need to repent of that and take that responsibility far more seriously.
