So whenever we're thinking about energy states, it's lways more stable to be more low in an energy well, so that's why it makes sense that it's favorable, in fact, to have an electron interacting with the nucleus that stabilizes and lowers the energy of that electron by doing so.

So you don't want to put in a negative energy, that's not going to help you out, you need to put in positive energy to get an electron out of the system.
