Those are good indicators the company is going to fail, so those are things to keep in mind. However, those things can change / be turned around and aren't individual deal breakers. A founder that focuses on raising a round instead of getting customers, in isolation, might be acceptable (or even smart) in some instances - discomfort with the founder him/herself is a non-starter in isolation. Get out. Now.

Now "how to quit a startup" - that's important too! Give notice, document your code/BD pipeline/whatever, ask for mutual releases of any potential liability if you can, and leave with a smile and don't say a bad word about it to anyone.
