The expression "to/until the bitter end" means to continue doing something until it is completely finished, even if it is difficult, painful, or unpleasant. It is often used to describe situations where people are facing challenges or obstacles, but they are determined to see it through to the very end, no matter how hard it may be. This expression can be used in both positive and negative situations. For example, a sports team might play to the bitter end, even if they are losing, or someone might stick with a difficult project until the bitter end, even if it takes a lot of effort and time.
