I really dislike Adam Smasher as a character, and no it's not because he killed the Loli or whatever. He reeks of "Oh Sea Donut Steel" even in the tabletop. He pretty much goes in the face of everything in the game, both rule and lore wise.
The world is suppose to be highly deadly where if you're dead, you're fucking dead, but Smasher (as per lore) has a bunch of back up bodies and save ups of his brain hanging around if one of him ever gets destroyed.
He can endure cyberpsychosis because he was already a psychopath but that's not at all how it works in game and in lore, you're suppose to have heaps of humanity to have any significant cyberware on you let alone if you're gonna fully borg out. Your humanity (interpret that as you will) is the only thing keeping you tethered to reality, but if you start with no humanity then you just go wacky right away. It even goes against the new fluffed up version of cyberpsychosis, because any existing mental conditions simply compound your cyberpsychosis, they can't block or replace it.
According to the anime at least ( and even in the Cyberpunk 2077 game to some degree) he is very resistant to hacks, despite that's suppose to be the one vulnerability to full on borg characters and he is never shown to be some super genius net runner who can counter hack on the fly.
Arasaka who prizes discipline, obedience and loyalty above all somehow decides to keep around a guy who has a history of being undisciplined, disobedient and not loyal to anyone, not only that but they put him in charge of protecting the head of Arasaka.
They know they can get away with it now that all the gaming shills-i mean completely ethical journalists are back to sucking their cocks. So why wouldn't they? Your best hope is it doesn't exceed 10 bucks.
