If roxas killed xion and axel dead did roxas eat ice cream by himself

Spoiler***

Although I have not finished 358/2 Days I'm pretty sure Roxas would kill Xion. Of course I'm not sure. Axel doesn't die until KH2 I don't know why you think he died before that. By then Roxas wasn't eating ice cream at all. He was taken away to be his part of Sora... I hope I helped you
