The majority of attacks by the homeless in big cities seem to be towards women, which implies that their brain is reasonable enough to understand the benefit of picking a physically weaker target
Maybe not quite as crazy as they seem, but also not committing hate crimes against women because reasons
Edit: I’ll expand on this. There was an attack (
https://www.washingtonpost.com/news/...-zombie-lived/) by a truly psychotic person (young man, early 20’s the age for the onset of schizophrenia to manifest, which is what he had) where he was eating someone’s face off. This is different than the homeless person who had ate someone’s face off years ago, that person was believed to have been on a drug like bath salts whereas this young man most likely not
He randomly attacked a man and lady in their front yard and as he was eating the face off of a prone man on the ground, a police officer was pointing a gun at his face, yet this crazy young man seemed not aware. A police canine unit was also attempting to pull him off the man, yet this crazy young man seemed not to notice or care, and ripped his own arm out of the dog’s mouth 2 separate times, which completely shredded all the muscle and tendons in his arm, yet he seemed not to notice or care
After treatment the young man explained that he did not remember the actual attack, but that before it he believed he was being pursued by demons
A forensic psychologist was able to get him off on an insanity defense because the young man’s mind was so completely psychotic, that it no longer had any idea of self-preservation during the attack (hence the no fear of the gun or even realizing a dog was attacking him)
So a person that deliberately picks a weaker target might not be at the same level of psychotic
