>>93163003Well, we don't really know enough of Hans to know what his real motivations or thoughts are. There was a tie-in book that painted his home situation as really horrid and abusive, but it was written so badly and contradicted canon in so many places I wouldn't put too much weight on it, and would rather wait for an actual canon installment to provide insight into who he is.
However, we do have Jennifer Lee, the writer-director, saying that she sees Hans as a "tragic figure, and a consequence of being raised without love":
https://www.reddit.com/r/IAmA/comments/1xj4n5/hi_reddit_we_made_frozen_ask_us_anything/cfbuo8u/and there's Santino Fontana, his VA, saying in an interview (before Frozen 2 was announced) that the writers have told him that "we have an idea, we want to bring you [Hans] back and redeem you":

(Though that's maybe overanalyzing a bit.)
So, no-one knows what they decide to do with Hans in the sequel, they could write him almost any way they like since we learned so little of him and his real thoughts in the first movie. They could just not bring him back at all, or have him turn truly evil. However, these little bits of insight from the crew are enough for shippers to build headcanons and interpretations and au fics on.
Besides something doesn't need to be canon or even feasible in canon to be shipped, see Elsanna for example, or crossover ships. Shipping is about feels, not about what's canon.
We'll see what happens when the sequel hits. But someone asked a shipper to explain the draw of the pairing, so I answered that with my own personal reasons. That's all.
