I absolutely hate spoilers and the people who drop them so casually, so won't give any real elaboration whatsoever until the actually relevant chapters are released, but to everyone saying they'll drop the manga over this character I'd encourage you to continue reading at least until around the midpoint of volume 3 for the full explanation since there are actually several. I actually like how the author has handled things when I think about the characters and their directly stated justifications for their actions as well as the details you can surmise indirectly, it makes a great deal more sense in the end.
Regardless, thank you all for reading so far.
