Well it was kind of explored in Shippuden later and his friend who gave him the eye really turned around his outlook on being a ninja. The Kakashi as a kid would've let his comrades die, the teammate who helped him turned that around. One of Shippuden's few good points after an overwhelmingly bad showing. I think Sakura would have an opportunity to express how she feels to him, just a matter of where and when. I think in the manner of Mako and Asami, Sakura may bring it up every now and then or have reservations. I'd find it cute if she hates being apart from him after a while once he starts taking notice of how she's blooming into a fine kunoichi and a woman. Reminds me of when Sakura asked Naruto how grown up she was in the beginning of Shippuden, try asking that to a man with some real moves! Hopefully Naruto won't call Ino fat but I mean that midriff is telling a whooole 'nother story >.>'' 

Yeah not much more you can do. If you're not able to do like 4 paragraphs for at least one character, or three in a more critical case where little is happening, get out of advanced. Just my opinion though.
