The father is one of those people who are religious extremists & fanatics who see sin everywhere and in everyone outside themselves, not realizing the sin is really inside themselves, in their own mind & heart, ie. external psychological projection reflecting their own inner issues & their own judgemental 'sinful' (mind & heart full of sin, hence always thinking of and seeing sin everywhere) nature.
If someone says something nasty about you, it doesn't mean you're nasty, it means he's nasty.
If someone says something nice about you, it doesn't mean you're nice, it means he's nice.
Someone who is sinful sees sin everywhere & in everyone around him.
Someone who is evil sees evil everywhere & in everyone around him.
Someone who is good sees goodness everywhere & in everyone around him.
Someone who is loving sees love everywhere & in everyone around him.
