We're all broken and wounded, some minimally and some very much. People can gain valuable and deep wisdom from being broken and wounded, and we can learn from their experience. Having worked with broken for years, I agree you can't not be impacted -- it's important also to have clear boundaries and take care of yourself or you're not of much good to the other and will likely burn out quickly. I embrace imperfection with an open heart when I care and relate to what is present and not to assumptions, expectations, prejudices, predictions, or preconceptions about what is present. What helps me welcome uncertainty is knowing that uncertainty is all there is. We live in uncertainty. It is always uncertain what is going to happen, and I am more content accepting that than fighting or denying it.
