The way I read this, I would rephrase your question as "Is it OK for my first venture into the working world to be that of burned bridges and distrust". So, no, I don't think it's OK.

It takes a lot of emotional energy on both sides of the table during the hiring process. If a job isn't grabbing you to the point of wanting to sign right away, than tell them so. Tell them you're exploring your options and you can't sign right now. They'll probably move on, but perhaps something will open up with them again down the road.

It sounds like you're not hurting for offers. I wouldn't start off by pissing people off.
