Wow, terrific, wonderful, congrats on new family member.
Neutering is best to do to avoid testicular cancer down the road, in puppies having this done at an early age most times does eliminate marking only because some male puppies have not started to mark, reason to get them Neutered at a young age. At 3 y/o and has now become a habit, I doubt that it will stop the marking, but, it will eliminate aggression and dominance. Cody is my first boy, I don't have these issues as he is an only fur child. I know and have known of ppl that have 2 males that fought and were aggressive towards each other, after both were neutered the fighting stopped. I advise to neuter for health reasons and eliminate aggression before it starts. Good luck with your little prince, piccies please when you can and please keep us up dated on prince's new life in his new home with his new family and baby new brother. This new boy may help Thor cope with missing his mommy so much, a new buddy to play and wrestle with, so much fun to watch two fur kids playing.
