Well, what does the text go on to say? Brutal, this is a word only used here, it means not tame, fierce, savage, when you use it of an animal, it's an untamed beast, wild animal, just wild, people are wild, haters of good, literally, not lovers of the good, you put an A in front of a word, it's an alpha privative, alpha negative, philos, agathos, not lover of good, treacherous, people are traitors, they're betrayers, they're Judas's, reckless, oh, they're rash, they just fall forward, they fall headlong, it's like they're so hasty, so rash to do things, they don't think about it, no consequences thought of, running into it, pell -mell, hither -thither, conceited, lovers of pleasure rather than lovers of God, they're philedoni versus philotheoi, kind of a word play, they have pleasure in the center, not God, holding to a form of godliness, although they have denied its power.
