A person may be a devout Jew, Christin, Muslim, or whatever and be a disgusting human being. Religious devotion is about belief, not behaviour.
In my opinion, if Joe Biden is good man, it is not because of his catholicism, but in spite of it.
Believers like to claim say Muslim suicide bombers are not ‘true’ 'Muslims or that pedophile priests are not 'true ’ catholics. Nonsense of course, identifying as a member of a specific a faith is simply about belief. Hence the suicide bomber may be a bad Muslim, but a Muslim nevertheless. So too the pedophile priest may remain a practising Catholic, just not a good one.
In the1960’s when I was a teen, hypocrisy was one of the major fault we saw adults. So course, we smugly exclaimed that we baby boomers were going to create a brave new world. And haven’t we done a bang up job! No doubt the current crop of adolescents accuse us of the same thing, and are just as right.
These days I realise that we human beings are deeply flawed by any moral ideal one chooses. That we lie often, and can be hypocritical are simply parts of the human condition.
Speaking of myself and all the people I’ve met, we are neither especially good nor especially bad. That includes the annoying apologists we get here
