Undoubtedly he had. But those truly close to him are not likely to rush forward. Those who do will most likely be those who didn’t know him well and are attracted to being on TV or who need to distance themselves from him. It’s a cultural thing. Norwegians are generally not so eager to open up with their feelings with strangers as Americans are.
That he considered himself a conservative is clear from his political activity and posting. Lone wolf? Dear God I hope so...
Do you have links to his political activity?
