Disclaimer, I think murder is wrong you fucks, so don't try to spin my argument.
That said, I can understand this Laundrie dude losing control and killing his girlfriend. I think it's horrible, and him being capable of it puts him in a certain category for sure, you imagine someone with possible mental issues, or at the very least someone who is unable to control his anger or impulse.
BUT, I would argue that MOST of us are capable of losing control if pushed far enough, and as much as we don't like to think so, I believe most of us are capable of taking a life under the right circumstances. So while I would want to see him punished accordingly, and certainly go away for a long time, I can also admit that under the right (or wrong) circumstances I imagine I would not be immune to making such a mistake.
The part where I can not relate to this man whatsoever is his denial and refusal to own up to it. I mean he's standing there basically red handed, he's had how many days and weeks of driving across country to search his soul. And he couldn't find enough decency inside himself to at least man up to what he did and give her family closure. I mean even if he killed a complete stranger that should be the case, but the woman he supposedly loved? I cant understand that at all.
I guess someone might say I'm not taking into account all the shock, or whatever else you'll tell me he's going through, but I don't buy that crap. He's spend 20 something years of his life appearing like a normal well adjusted young man, so it's not like he's this confused mentally ill dude who doesn't know what he's doing. It would be more accurate to simply say he's just a coward who despite his outer persona really had very little going on spiritually.
But aside from the right thing to do, it was just fucken stupid. I mean he wasn't getting away with it, there was zero logic behind it, it just seems like some cowardly gene kicked in and no amount of self reflection was gonna shake it.
