You may choose which ending suits you

Menma had snuck his twin from the hospital and is now in his basement with a subconscious Naruto. He had thought that by mentally abusing Naruto more and more he would eventually kill himself. Surprisingly, no. So instead he was using Naruto as his personal mind slave, which means the he could do anything of which his twin pleases, having not a single care.

Menma was going to use Naruto for something he always wanted to do:

Kill Hinata Hyūga or Sasuke Uchiha

He would love to see their reaction on how their dearest friend take their life away. But since Naruto now has a simple mind, he can only do one thing at a time. His choice?

Hinata Hyūga

Menma walked up to the lavender haired girl and first greeted ( manners ).

"Do you need something, Menma?", she asks, with such innocence. 

"I need you to stay right here. Naruto has a surprise for you", he says, running off in the bushes. Hinata blinked two times, amazed on how her beloved had improved progress so quickly.

In the distant bushes, Menma gave the blonde his orders then handed him a machete.

"Do it..."

"Kill....Kill....Kill...."

Naruto was now silent, creeping up behind the Hyūga with such stealth. He covered his chakra making it harder to sense. Hinata looked around thinking she heard someone mumbled: "Kill", repeatedly. She was in Konoha's forest with a flowercrown on her head.

"N-Naruto-kun?"

Menma then appeared in front of her, distracting her from the blonde's mumbles. Naruto was right behind Hinata as he nuzzled her neck.

"Hinata...."

"Naru-chan?"

"Kill...Hinata", he muttered. He rose the machete right above her head, as the Hyūga's heart shattered... she would never fight her beloved, even if her life depends on it... which it does.

"I'm sorry, Hinata...", he whispered in her ear before blood splattered over his clothes. Naruto stared down at Hinata's corpse, eyeing the machete that was plunged into her skull, seeing the blood pour out.

To burn the evidence, they burned the corpse and the knife.
