Can I ask why you wanted to murder your family? If you don't mind explaining.
not sure it's a justifiable reason but... well, we've always been on bad terms, my parents were/are quite abusive and I always felt oppressed by them, to the point that I gave up on my right to choose things for and by myself so that I could satisfy their wishes. I felt trapped to them, and couldn't cbt because of how my decision would affect them, and then I thought that maybe I could just take them with me, so that they wouldn't feel a thing about it (cause they'd be dead) and neither I'd feel guilty. Plus, I don't think their deaths would make a huge difference on the world. It was obviously not the best outcome for them, but it wouldn't be as bad as dealing with the fact that my actions would have consequences to them, because somehow, I felt worse about making them live with grief than about killing them.
it's a fucked up thought I guess. but well, I had it, no reason to deny.
I just gave up on the idea because of my brothers. It wouldn't be fair to make them pay for my parents mistakes, nor for mine. I hate my parents, but I guess they kind of like them... Plus it'd be to troublesome.
