Yea but I think the differance is only there right now because no 'innocent' person has stood in the way of R!Syaoran's desire yet. If a seven year old had put the seal of death on Sakura opposed to FWR I don't think it would have made any differance to R!Syaoran wanting to take him out, since as long as that person or thing is a hinderance to their desire they will do what they have to. If there's any distinction between the two right now I think it's that R!Syaoran does take other people's desires into a bit more consideration than FWR ever will. Like how he didn't kill C!Syaoran in Tokyo because it's what Sakura desired and maybe even why he didn't take R!Sakura's hand just now. Where FWR has always been most like Taishakuten imo~

*has image of FWR and Haruka smoking, drinking, and discussing philosophy* Good times. lmao xD
