Should I Keep The Scar?

I think he looks good either way.

whenever there is potential for a cool scar its a keeper

How'd he get the scar?

Definitely keep it. I wish we had more scars, including body scars. I keep meaning to make more scarred sims. My recent vampire sim had a scar but in the first instance he died when I took my eyes off the screen for a bit, then I reloaded and went back to a previous iteration of his save, and that time he glitched to the point I had to stop playing him. If only I was able to focus on one save for a significant period of time before I get bored...

It looks good. Makes him look mysterious.

It looks good on him! (He is a handsome sim, either way.) Gives him a bit of a tough or mysterious feel.

One of the spellcasters I just created got a vampire skin detail when I made her in CAS, and I don't know how to remove it. I decided just to embrace it and maybe I can even come up with a cool story for why she got it. So I vote yes, scars can be cool and have a backstory too.

The scar gives him a story to tell and some individuality in the world of Sims who are all conventionally attractive in all the same ways. Gives him some swagger.

Definitely let Erik keep the scar. I think it makes him more than "just another pretty-boy singer," and might actually increase his popularity with a wider range of fans who might identify with a dude who looks like he's walked some mean streets.

It might depend on why he got it.
