While we're supposed to see the lawyer's actions as heartless as they don't see Robocop as a person, it makes more sense when you remember how he handled things at the end of the first movie: just before the shoot out at the steel mill, Clarence is flanked by two goons with a fourth driving their van. Despite being able to kill someone with a single shot, Robocop fires three rounds into the same guy even though those same shots could've taken out Clarence and the goons. Lewis wouldn't have been hurt, and the mill would've taken less damage. The same problem happens with Dick Jones: Robo didn't need to fire that many shots and drop a former exec out the window like that. They're not only concerned about legal issues and drumming up interest in Robocop 2, but they're protecting themselves from a cyborg that could violently kill people who've pissed him off and cause collateral damage as a result.
Cain and his goon's attack on Robocop starts with Hob blowing off his right hand. It starts the same way as Murphy's death in the previous film.
It makes sense that Johnson would be opposed to altering Robocop since it was the last thing his friend Bob Morton ever worked on. For all their mutual faults, the two genuinely seemed to care about each other as friends.
Notice that in the final firefight, Cain shoots several news teams as well as cops and security men. This of course is supposed to represent how reckless Cain is by shooting people indiscriminately, but that message falls a bit flat. Cain has "the best eyes money can buy" and a targeting system to go with it. He shouldn't be able to miss so widely from the people shooting at him, so why would he waste shots on camera crews? There could be another reason for it. Cain shooting news people may be entirely deliberate, a "don't look at me"-reaction to the news cameras. When the rebuilt Cain destroyed his old gang, he had a touching moment with his former girlfriend, but when the conversation went in the direction of sex, Cain freaked out and killed her brutally. Cain shooting the news people may be a body image issue instead of mere recklessness.
Tying into that Cain didn't kill Angie because she talked about sex, but because Cain is a Sense Freak and he couldn't feel Angie stroking his hand/claw.
Despite being part of Cain's Nuke Cult, Hob is never shown actually using Nuke. It's most likely Cain forbade Hob from taking any Nuke since he was a child.
The development team at OCP apparently learned their lesson from ED-209's vulnerability to the Cobra Assault Cannon. Cain is now presumably armored like a tank and thus highly resistant to small arms. Additionally, the real-life version of this weapon — a .50 BMG rifle — is typically inadequate for anti-tank warfare.
The cartoony whistling sound effects as Robocop and Robocain fall off the top of the OCP building aren't for the sake of being funny. They're produced as Robocain falls because there are numerous holes in his superstructure acting as whistles as the air quickly passes over them, just like the sound of bombs whistling as they fell during World War Two. This was a favored tactic of the Germans for psychological warfare.
Since OCP has the whole Third Reich vibe going on with its flags, the uniforms of its security guards, etc., it's very fitting that their latest flop would be portrayed as a bomb in more ways than one. This is reinforced with the Walther PPK playing a role in the film as a villain gun, being Cain's favored handgun and a variant being featured in one of OCP's commercials of questionable taste where a character uses it to commit suicide over choosing the wrong data service provider; a commercial like this getting past quality assurance also indicates that the OCP staff are losing their sanity and the company is on the verge of collapse.
Murphy convinces his wife that he's just a machine made to look like her husband. But now the poor woman possibly believes a soulless killing machine with her husband's face stalked her and her son for reasons only it knows. That's way more horrifying than a machine that's possibly her husband driving by because he missed them. If she wasn't already going to sue before, she definitely should now. Imagine having your dead lover's face put on a killbot, then that bot stalking you. It seems like the worst possible explanation they could have given her.
Cain's brain and spinal column getting suspended inside a jar with fluid already doesn't look like a fun time, but only his sense of sight remains, leading to some serious sensory deprivation. That situation and Cain's Nuke withdrawal could be a profound kind of torture for him.
How a child Hob's age can be a sadistic criminal aligned with someone like Cain makes a lot of sense when considering children getting sucked into violence in real life. Perhaps Hob was a homeless kid that Cain lured in with the false promise of a home before brainwashing and indoctrinating him into the Nuke Cult, or Hobb came from an abusive home, or Cain killed Hob's family. Maybe Cain sees having a kid like Hobb in his ranks as a means to show how strong his power is; if he can make an adolescent follow him without making him dependent on Nuke, there might as well be no limit to the kind of people he can corrupt.
Was Hobb's personality different from his current one before meeting Cain? How much psychological damage has been done to this kid to make him this way?
Also, being a kid in a place like Old Detroit might be a contributing factor if he grew up or lived there. The rampant crime and bloodshed are highly likely to tear someone down emotionally, especially a kid who's still developing, and make them an easy mark for someone like Cain.
