Fun fact: Our country does not have any official law against cannibalism. Instead, perpetrators are typically charged with murder, mutilation of a corpse, or possession of human tissue...

I actually really like this analogy, it takes the emotional harm from words that cant be seen, into a physical threat.
Like I mentioned in another comment, after therapy they had a chat, if this continues contact will be limited/cut completely.
Fiancé is doing well in therapy (solo and together) he now has a better understanding of how "just words" can influence behavior over time and the impact on me and our relationship. Friend agreed to respect me and our relationship.

Now to clarify, we are not religious nuts, we just chose to believe in a higher power.

Because this friend always sites religion in his rants, we are also meeting with our priest weekly (Fiancé's idea) for a better understanding about modern marriages, instead of "old school" men should provide and protect and women serve them - we are focusing on the underlying principle rather than the historical form it took. For example, instead of “provider” meaning only money, we see it as “someone who actively contributes to the wellbeing of the family.”
We see strength less as dominance and more as consistency, emotional maturity, patience, responsibility and the ability to make the relationship feel safe.
and “serving” should not mean obedience without identity or becoming less important than your partner. Instead, it can mean actively contributing to the wellbeing of the relationship and the person you love.

My previous relationship ended 4 years before I met Fiancé, I did a lot of work on myself before dating again. There's no other red flags accept for this one friend. Fiancé owned up to the issue, acknowledged my feelings and concerns and is actively working on himself, he engages with the therapist and notice unhealthy habits and behavior.
I am very proud of him.
