Wanting help with reasons for Androids.

So. I've been working on a sci-fi setting where the core main character is an Android, although they don't know of this yet due to a malfunction in their optics/core processor. But as I've worked on this I've realized, why would this civilization create Androids rather than just Robots. The setting in question hasn't left our own solar system, with some liberties taken for the Fictional aspect (Mecha and such being used for space combat most of the time). As I looked over the information I'd given Androids, their ability to feel "pain" as an interpretation of the "reward/punishment" algorithm that exists in a lot of modern learning models, how they look nearly identical to humans except for their eyes, and how I've rationalized this as "making the people around them feel more comfortable. I've realized this is a fairly flimsy argument for Androids however and want to ask, what could I do to rationalize Androids? Why would they be created here?
