I wish relations mattered more

[Xeizzeth]

I wish relations mattered more besides being a mood debuff upon their brother/mother/father being killed in the raid when they attack your colony. 

I wish if they attack your colony and find out that your colony has their relatives they would refuse to attack, ally with us and fight on our side, sabotage enemy raid and then join us, etc. 

Right now we see fathers mindlessly shooting their sons just because they happened to be on the opposite side of the barricades. 

And recently I had the brother of my colonist attacking my caravan, and when I made sure everything will go smoothly and I will capture him safely he could not be recruited as he was "unwaveringly loyal to their faction", and then, on the next ambush he was shot by my colonist, and surprisingly, their relation is gone now: 
 
I am showing you a "social" tab of the prisoner (brother of my colonist) to show you it's blank clear now. 
The same with my colonist. Their relation is gone. I bet after me receiving a message of him being "unwaveringly loyal". 

Looks like this prisoner and my colonist said to each other "you're not my brudda anymore", and decided to stay enemies forever.
