Maybe not, as some of the example usages in here, but it still has a negative feel to me. Is there some positive way that can be used instead?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
It doesn't have negative connotations in itself.
Abraham Lincoln was born in Kentucky, and ended up the 16th president of the United States.
There are no negative connotations there.
If you keep that up, you'll end up in jail.
Here, there are no negative connotations from "end up" either. If we replaced "jail" with "the White House", it would be a positive sentence. "End up" has no bearing on the positive or negative connotations of a sentence.
