He didn't "try to do the right thing." He was bored with the predictable outcomes being a pacifist, so he killed them to see what happens in many many ways until that got boring as well. (sad face)

Also, he didn't tell us because it's a personal issue, and only Chara would hear it because they were his "best friend." You don't go around and tell random people you've your tragedy and expect them to care lol.

Anyways, yeah, Flowey is just a twisted Asriel, and Chara's determination did not create Flowey.
