Scar not wanting a soulmate and sticking with animals kind of makes sense to me in a way. First during Last Life he was alone and when ever he made a friend/ had people hanging around him. All they wanted to do was use his stuff for their own gain. Then later leaving him there yearning for them to come back. Scar even says “I give my lifes, I give my resources and then they all just leave me.” [Clip: https://youtube.com/clip/Ugkxm0UKBDi28OQAAeo3s8dKXDUxcEMGk78p]
Not only does this man have abandonment issue, but also has trust issue. And during Double Life Scar is in the same boat as Jimmy. On how if you have either of them as your soulmate you are bound not to last long in the game. He may not be a canary in the coal mine. But he is seen as something/someone that will get you killed. Which means Scar and Jimmy are rated low on soulmate survival to others. Which could lead the man to see himself as a burden and even have self esteem issues.
Which is way animals are the best living beings to Scar since they will not mock him about being accident prone and won’t leave him unless taken from him by another player. So I understand why Scar may find them more reliable and caring then the players.
