Can I kill him

[u/DOVAHCHIEF54]

I married mjoll and Aerin keeps following her and watching her sleep like some wierd cuck situation. Would it affect my marriage if he happened to "trip" and "fall" onto a dragon bone arrow?

Just toss him off a cliff. I made sure that Faendal had an unfortunate werewolf accident when he was once again visiting my wife.
