Interesting, I was binge watching Mel videos today, and I was just thinking she has to be one of the best ambassadors for Islam.
Well, if the guy is a metal head, this would soften him up or he doesn't have a beating human heart. (Although my favorite of her's is the "Soothsayer" cover. I'll admit I got a bit teary-eyed. It's an emotional song.)
I mean her Death Metal shirt is pink with a rainbow and she's cute as a button while shredding monster power chords and lightning runs. And you can watch some of her vlogs. To me everything about her communicates kindness, compassion, forgiveness, everything you're talking about. Nayzak's art is another good model like that.
Anyway, I wouldn't think this is the best place for your question, but a google search for me came up with this that looks helpful for you, since it's quoting sunnah (sayings & teachings of the prophet) for the things you are mentioning in the context of building positive relationships with others.

Edit: Or if I could give any advice, do a search with "sunnah" and any of the terms you mentioned. If we have any Muslims that visit this side of the forum, I'm sure they'll have even better advice.
