All this speculation about drugs, psychosis, an obsessive passion for CR, social problems, lonliness, being ridiculed.....
NONE of those things have been suggested by the people who know him personally.
NONE of these things are borne out by examination of his online messages or the messages of his friends, before or after the crime.
In fact, those who claim to have had contact with him, such as those whose children know him and the person whose son in law worked with him, have all described him in the opposite terms.
He has been described as a sensible kid with a good job, this a good sense of humour, a polite and friendly nature and a nice circle of friends.
I know we are all here trying to mkae sense of crime and trying to understand if and how it is possible that the accused is guilty, but mking stuff up about him that is not based on the known facts about him is not going to help anyone.
