For me, the worst kind of "EVIL" and "SIN" is "MY OWN".
"Judgement begins with the house of God", 1st Peter 4:!7-18, because of "the sin that so easily entangles us" Hebrews 12:6, that we are so weak to giving in too and enjoy, and God's discipline is meant to separate us from that sin and save us. "For whom the LORD LOVES He disciplines", Hebrews 12: 3-17.
Personal sin over time is exhausting, and fighting it is so stressful, and the failure over and over to control it is so discouraging and disappointing.
And not to mention how hard it is to deal with the discipline of the LORD, that can be just PURE TORTURE?
You cry out to God and tell Him how much you hate your own sin, and beg to be released, and praise God, maybe after many years, even decades, of constant struggle, with Gods massive help, you joyously overcome.
YES, I have BEEN there!!! Not there any more ?. PRAISE GOD.
