Its possible theres more to it but so far he said that he was irritated by blondie's hypocrisy. And that his hypocrisy made him the worst of his family. (Even though he didnt even care about what happened to his brother).
And the MC's sister said that she agreed about the "fake kindness" making the situatoon worse.
I get that this was a situation made by the author to expose the "good brother" true feelings. But the redhead's motive are really weak for going this far.

Omg the blonde kid is just being polite. (I guess he was overdoing with the MC'sbsiter) but that redhead has some screw loose.
Yes he does it because he wants to be loves, SO WHAT? Bitch ya bro got the money and he happy, and you dont even care anyway, WHATS YOUR DEAL??? This story is getting stupid
