My father, I estimated, brainwashed to display even stronger side of his already weird gaffes around people to hurt himself infront of others

I believe he alone is MK Ultra victim acting often times without realizing. They(niece, her husband, mother, sister and others) did so this to gain support for crime against one which was translated to me as "best not to have him around when thing comes out as one is trouble only - mother wants her last years in piece too".
