Should I make a new YouTube account?

Sooo I'll have had my current youtube account for 7 months on May 20th. I use to make videos about celebrities and I now have 158 subscribers. Well I've always liked this one cartoon show and I downloaded some episodes and stuff but I never really made videos about it. Anyway, just recently I've realized that all the celebs I make videos about are really bad influences or bad rolemodels and so on, so I decided I wanted to quit vidding about celebrities and to just vid about the cartoon. The problem is, almost all 158 subscribers I have are subscribed for celebrity videos, so there really isn't a point of HAVING the subscribers since they either won't watch or won't get my new videos. Plus I don't want to watcn any more celebrity videos, so I unsubsrcibed from about 190 people, only staying subscribed to those who make videos of my fave cartoon. I really don't want to tell my subscribers what's going on cuz some of them are really annoying and will try to make me continue my celeb vidding or theyll get mad because I unsubscribed and such. Plus, all the popular youtube video makers (like mileysnuggle and about 10 others) are leaving or already HAVE left because they lost their video clips, their computers crashed, personal reasons, etc. So it's not like I'm the only person quitting. So my question is: should I delete my current youtube account, the one that has all the irritating subscribers and drama and stuff, and just make a new account that is just for my cartoon videos? I AM over the celeb vids and stuff, it's just that i have 40 videos up and some are pretty good and got a lot of views and even tho i don't vid celebs anymore, i'm still proud of those vids. so please tell me if i should delete and make a new account or not, and please explain WHY. i won't choose your answer as best if you don't explain why you said what you said. thank you!
