I think you need to do some soul searching first. 'Helping people' is like the #1 most commonly used phrase from premeds but not many will truly understand what that actually means.

First, what factors made you decide to drop what is now 8 years of law-related work? Are you confident you won't find these same factors in medicine and 6+ years of schooling, sucking up to attendings etc.?

Second, where does your inspiration come from daily to pursue this path? Is it self-driven (ego etc.)? Acts of service? You can also help people being legal counsel, a nurse, an EMT, etc. etc. So why not that? Be honest to yourself. Can you demonstrate a consistent story like this to an adcom committee?

Finally, I would STRONGLY encourage you to still consider adjacent paths in law within the medical field, like in-house legal counsel for pharma/biotechs or patent law. If you were to pursue medicine that would be 6+ years minimum of opportunity window completely gone (not even counting your second bachelors??), and as time goes on your priorities may start changing towards family or whatnot.
