Pride is one of the Mirror traits in the Joseph: Collapse DLC. Its free first level gives Joseph Healing Syringes that refill over time, and the later levels raise maximum health in five steps.
Level 1 hands you Healing Syringes that come back over time, so you always have some healing. Each later level adds to Joseph's maximum health, which lets you survive more hits before a run ends.
Walk up to the Mirror in a safe house and spend Penance, the currency you earn in Joseph: Collapse. Levels unlock in order, and each one costs more than the one before.
Yes. Extra health is one of the best ways to make runs last longer, especially before you have strong weapons.

Greed (Joseph)
Lets you keep more currency after dying, and at the top level recover your full inventory where you died.

Sloth (Joseph)
