In a virtuous life, evil is suppressed and good surfaces; but the evil is still there.
The bad sanskaras remain and have to be worked out, if not in this life then in the next or the one after.
In the spiritual life, both good and bad sanskaras express themselves, and both get nullified.
Everyone, no matter how depraved, can gradually become better and better until he becomes the best example for all mankind.
There is always hope for everyone; none is utterly lost, and none need despair.
It remains true, however, that the way to Divinity lies through the renunciation of evil in favor of good.
