mikehall12382: The expression ‘Yimach Shmo’ which means ‘ may his name be wiped out’ I have heard is not meant to be applied to any Jew however wicked he is. Please see the other thread ‘ The evil monster is still a Jew’ for discussion of this and a source too.’
It is a basic tenet of Judaism (and there are also scores of examples in Jewish history and literature) that ANY evildoer can repent and achieve atonement for his sins however many or degraded they are. It is not a quick and easy fix – but it is achievable. No Jewish soul is outcast entirely.
