Hawk would take it badly because he already remembered Hatter telling him that his friends only see Alexiel in him and not the real him. While that's not a problem in Decollage because nobody even knows Alexiel, it has given him some insecurity. After all, Uriel kept calling him "Alex" while he was around. He's afraid if there was another version of himself, maybe people would prefer that one and maybe it would be less crazy and easier to manage and get to do what people want. So yeah, Hawk does have a bit of Setsuna's self-image issues. :x
