There are caveats where profitable means "more than you would lose by folding" e.g. BB play, but fundamentally folding all unprofitable hands and playing all profitable hands will increase your winrate.
If you add hands that are -EV to your range but they make other hands in your range more +EV then should you not add them to your range?
