Two questions about a profile

I want to study Computer Science/Business/Economics (one of them, maybe a mix of two, the point being those are my three interests).

My Computer Science is more of using code to assist with economic/business transactions (in college that’s what I’m trying to go for). Would it hurt if I did not do Intel or Science Fair for computer science, and instead only opted to remain at the school-level (my school has a Computer Systems Research Lab)?

Also, do colleges care about how your character? A lot of kids just do things for the hell of putting on their college app, but me, I do a lot of philanthropy and community service cause I actually feel blessed to be where I am and I truly do like giving back.

Thanks
