Yeah, such a good buddy. Killed a dude and made a girlfriend out of his body. He killed him in fact, rewrote the target's history, that is, the guy literally never existed except in the killer's memory. Clever, I must say.
I wonder if his "girlfriend" retained her old memories? If not, then that simplifies everything. But if she does, does she realize what a monster is next to her? I would hardly even call him a human. Love turns a blind eye to many things, but to such a strong outrage against free will, personality and the murder of "oneself" in the past, I doubt it. Although I can't say for sure. Love is a terrible force.
I hope she doesn't remember anything. It would be easier for me to sleep that way. And if she does remember, then I hope sooner or later she will collect the fragments of her old personality, gain access to this app and give her "boyfriend" his own medicine. Or just stab him with a kitchen knife in his sleep. For self-preservation, at the very least. After all, sooner or later he'll get bored with her and turn her into an animal or get rid of her altogether while he's having fun with his new toy.
The story is pure fiction, of course, but it still sends shivers down your spine when you look at the ease with which such psychopaths can justify any of their actions, as long as they don't get sued or get shot. "It's just fun. I'm not doing anything bad. No one will ever know."
The stories may be fictional, but the thoughts in people's heads are real. If such a person had such an app in the real world, how many horrible things he would do without feeling even the slightest bit of guilt. And these people are all around us. There are many of them. They just don't have the opportunity to do anything and escape punishment, so they hide and wait. For now.
