The guy was psychotic. He had what is termed erotimania. He believed that Jodie Foster had a relationship with him, and tried to kill Reagen to impress her.
There was this idiot by the name John Hinkley who thought it would please Jodie Foster if he shot and killed Ronald Reagen.
I don't like Reagen's policies or republicans praise of him and never will but its a sickening thought anybody would wanna assassinate a president when he/she has done no physical harm to that person in his/her life
Nothing about that seems to make sense! The Bush's are creepy! But I guess it's not surprising that they have ties to the Hinckley's since they also have ties to mass murderer Bin Laden (good friends with the Bin Laden family).
From a 1981 AP article:

A merger with Neil Bush's employer Standard Oil subsidiary Atlantic Oil and Vanderbilt energy (Hinckley's company)--lots of strange coincidences that I just discovered now!
