Tough question, at one time eating pork and shellfish was immoral or unrighteous according to the desert god YHWH. I love those things! So on a scale of 1-10? Who's scale? I think it would need to be broken down like this:
Kindess: 10
behavior with women 3
and so on lol
Righteousness is linked to morality no? it used to be righteous to have slaves but not eat shellfish in the OT. The only things that I would consider unrighteous would be those things that harm others or society. Murder, theft, and so on.
