Sphincter in the Sky

I’ve been reading up on this Las Vegas shooter dude.  What’s known so far:

-          Was an accountant
-          Worked for the IRS for a while
-          Had been a landlord
-          Made millions in real estate and gambling
-          Moved to a retirement community in Mesquite NV to be closer to Vegas
-          Liked high stakes video poker
-          Developed a romantic relationship with a married casino host to get tips on "ripe" machines
-          Girlfriend divorced her husband of many years and left her job to move in with him
-          Remained jealous of girlfriend’s husband to the point of insanity
-          Habitually verbally abused his girlfriend in public
-          Sued the Cosmopolitan Hotel in 2012 seeking $10,000 for a fall but appears to have settled before it was brought to trial
-          Collected weapons, including semi automatics and bump stocks to turn them into fully automatics
-          Appears to have originally planned to carry out his plan a week earlier at the Life Is Beautiful festival in Vegas attended by 50,000 fans (or earlier and elsewhere and bigger), but didn't go through with it
-          Stayed for free for a week in the suite at Mandalay Bay courtesy of the hotel (thanks to his high roller patronage), carting weapons and surveillance equipment up to the room in stages to avoid notice
-          Monitored for police and security on the surveillance equipment while he sprayed machine gun fire on trapped, festive crowd of concertgoers from on high, from the comfort, safety and remove of his 32nd floor suite, for 11 minutes, killing 58 men and women aged 20 to 67 and wounding 489 more, and stopping to kill himself only when the police loomed.
-          Killed himself before he could be reached to avoid any and every consequence of his mess.
-          Perpetrated an act that ISIS coveted
-          Does not appear to have been motivated by any ideology, creed or cause for "the greater good"
-          Looks like a total dickwad in every photograph I’ve seen
-          Is named Steve

Is it possible the guy is just a supreme asshole?   Do we have enough information to establish that?  If so,  then I think what we have is a mass murderer for the Trump era.
