Just like Aoi blamed Kariya, eh? A fitting end for her. Good riddance.

Not really. In the novels, he couldn't even recognize it was Aoi he strangled until the end. Kariya's brain was damaged. Let's not forget he had a stroke that paralyzed half of his body and is currently being eaten inside by worms:

As a matter of fact, Matō Kariya’s madness was the last fortress left to rescue him. In spite of that, he had even missed that lowliest aid at the last moment – the face of the woman rapidly turning deathly pale due to lack of oxygen was too similar to the image of the beloved woman he cherished so much in his heart – no, it was the very woman herself. At last, Kariya realized that.

“……Ah.”

At the instant both hands loosened up, a sound slipped from Aoi’s mouth.

Collapsing onto the ground with a thud, she had fainted, not budging an inch. Lacking even the sound judgment to differentiate the living from the dead, Kariya thought that just like Tokiomi, she had died.

“Ah, ah……”

He gazed at the hands that had just choked Aoi with all their might. Someone more important than anything else; someone who was the very meaning of his life – those fingers that had plucked that someone away stiffened like they belonged to someone else. But without a doubt, there was no way to deceive himself – those fingers belonged to him.

Like a peal of thunder, he realized. Those fingers squirming so shakily were just like the crest worms creeping about Sakura’s skin.

“AaaaaAAAaaaaaAAAAAAhhhhHHHHHHhhhHH…!”

He clawed at his broken face.

He tore his dried-up hair.

A scream escaped his throat. Whether it was a shriek or a wail, he could not even understand that.

Losing the last bit of sense in him, with only his animalistic instinct, Kariya desperately sought to flee; stumbling, he ran away from the chapel.

The man who had lost everything was greeted by the pitch-black darkness of the starless night.

He was too insane he noticed that was Aoi. Had he been in good condition, he wouldn't have choked her at all. In fact, he would have realized who was behind this (the novel states this later).
