Darkness or Light? Philosophy in Knights of the Old Republic.

But how do you feel about the fact that a Jedi cannot love? A Jedi must renounce everything.

You have to hide in basements, like Jole Bindo, Anakin, the male protagonist of KotOR 1, and many others :)
But in general, this is necessary to avoid the Dark Side. Otherwise, you won't even notice how it consumes you (as an example - Anakin, and the holocrons of some couple from Korriban).
