This was for the Headcanon Meme but I’m a bad person and it took me ages to reply, I’m sorry, I was just too tired in the past days ;__;
Back to the meme, this is a hard question since guilt (and shame) don’t seem to be Soren’s strongest emotions, had he had a different childhood he could have maybe felt guilty over the ones that inevitably die following his plans as a tactitian, or the one he kills as a soldier, as I don’t think he enjoys killing I also think Soren HAS morals, at least theoretically, but I’m going OT. For how he is now, since his whole morals revolve around Ike, I’d say that he only feels guilty when his actions put Ike in danger or when he’s failing him. The skirmish with Mordecai and Lethe in the first chapters of PoR is a good example, he says he’s sorry, but he’s not sorry for what he said to the laguz, he regrets his actions only because Ike got hurt (and clearly didn’t approve of what he said, even if he didn’t seem to be angry in the end).During PoR, Soren seems to be very unsure of himself and his role in the mercenaries, even before discovering he’s branded:Chapter 8:Soren: …Ike. I’m not sure what help I could be to you. What place is there for me in a mercenary company, anyway?and despite apparently not being concerned with his controversial opinions, he tries extra hard to be useful to Ike, probably thinking he’s only worth of living and being there because he’s decent at his job, and even if that must very rarely happen, I guess he would feel guilty over getting something wrong, or missing something, or not working fast enough, etc. Basically a big “I feel guilty because I’m not good enough so I’m not worth anything” which is understandable considering he spent his whole childhood being told so, even if he’s amazing at his job. I can’t find it but there was a “death” quote in PoR where he gets too injured to ever fight anymore and he’s ready to go away only to get surprised when Ike tells him that he can still help and doesn’t need to leave, he’s honestly shocked.
This more fanon but I also think he feels guilt over being possessive of Ike. Regardless of the kind of relationship you think they have, he shows hints of being quite possessive of him (and that’s only obvious, if you think how unhealthy and obsessive he is in regard
of Ike), but he’d probably try to keep it under control because he knows it’s wrong, he knows he can’t demand anything, and Ike could get annoyed by it, but the feeling it’s still there.
