Anomalies and oddities
Lex quickly realigned his mentality with his normal thoughts and vanquished any lingering impulses to manipulate everyone into self destruction. As a mortal, his random yet dangerous impulsive thoughts were along the lines of leaping off when at high place, putting his hand into a beautiful fire, or maybe walking into ongoing traffic. These were, of course, things he did not actually want to do, but random thoughts that would pop into his mind from time to time.
But now, as a cultivator, his random yet dangerous impulsive thoughts involved toppling organizations and manipulating the masses. Of course, there was still the odd impulse to walk into ongoing traffic, but even that was now more dangerous to those in cars than himself. Truly having power changes a man.
