That's probably it. I can get that unstable people can become crazy at the drop of a hat, but to go straight into baby murdering killer psychopaths in one damn chapter.. It's a bit sudden.
		
		
	 
That's the thing though, dude is basically like a high functioning sociopath, we clearly see he's basically completely batshit insane and obsessed but he's smart enough for long term planning and thinking, he knows he can't win anymore, she'll never be his and he can't kill her either, so he'll do the last option he got, kill himself in front of her so he'll forever stay in her heart in some twisted way 
I think we're supposed to take it as he was always like that deep down, he simply didn't had reason to go murdering people before
At least that's my take on it, murder was never out of the table, he simply didn't have any reason to do it before 
	
		
	
	
		
		
			I think he was a prince. Can't say I cared to look it up either.
		
		
	 
Right, I also can't say I care enough to look lol
