Why finn won’t leave his siblings alone

Like I do not understand why Finn won't just live his life he hate being a vampire and now he not so why are you trying so hard to kill them or make them human like go on someplace like it make no sense they said he always hated what we are well he ain't no more so why why won't he just leave them alone like wtf fr it's crazy like I really want to know why he tried so hard to find the baby as well like it's not your problem move on go live your witch life none of this concern him dahlia would of came for klaus and them not him if he would of left he annoy me so much like he go what he wanted not a vampire how he gonna try to make choices for them
