That is because most people completely ignore or have forgotten the ICA’s reasons for authorising all of Season One’s mission.
Instead people focus on how Diana rationalises the missions which is from a person who dislikes people in untouchable positions or abuse their power.
Diana’s own reasons for disliking the targets is the reason we are given because “They bad, we payed in money, you kill meanies” is a terrible motivator.
The ICA’s reasons for wanting every target dead are as follows:
Paris: While selling private government and military secrets is wrong the ICA killed IAGO because it jeopardised their standing with MI6. MI6 gave them a contract and the ICA did it to keep a business partner.
Sapienza: This one is obvious since Diana literally says the ICA would be abolished if the Ether Virus was ever complete and it is also her own reason for wanting us to kill Caruso. The only time the pragmatic and emotional motivations overlap in a main mission.
Marrakesh: Again while overthrowing a government to install a military dictatorship is wrong as is stealing from a national development is wrong they died because it affected the bottom line of an ICA affiliate.
Bangkok: A contract is a contract. Again celebrities using their status to lessen or completely avoid jail is wrong but this was just an ordinary hit. No different from Joseph Clarence really.
Colorado: This one was an ICA contract sent to kill a perceived threat to the organisation. The fact that they are all terrorists of varying morality is incidental. The whole gaggle of targets could have been a team of Penny Graves and they would have taken them out.
Hokkaido: This one was to kill a traitor, stop the distribution of ICA secrets and send a message to Providence. Again Yamazaki’s yakuza ties are incidental to the ICA’s purpose.
Patient Zero: Stopping the apocalypse. Believe it or not most ICA members probably don’t want to die from a hemorrhagic super-virus. Also everyone on Earth being dead also isn’t a boon for the “kill people” business.
Marrakesh Night: Again a normal contract, In fact Mendola is one of the very few completely innocent targets in the whole series and the only one that has a somewhat decent personality.
Sapienza Town Square: Again another innocent target although Bosco makes it really hard to empathise with him he is still a guy who has committed no crime other than being a dickhead.
Sapienza Promenade: A contract and the fact that Abiatti is a mafia crook and right-wing populist is almost incidental to the hit. I say that because Caruso’s fake motivation is based in Abiatti’s mafia ties and policies
H2: So the ICA have sided with a shadowy, sinister organisation that runs the world in secret in what seems like an attempt at dispelling the notion of the ICA as a moral organisation forever in regards to the new seasons.
Miami: The fact that the Knox family are weapons dealers and war profiteers is again wholly incidental from the ICA’s motive for the hit. Providence wanted to stop a defection the ICA sent their top agent.
Santa Fortuna: Cartels, drug production and smuggling are bad and that is obvious but the only reason we killed more Delgado clan is because they were central to the Militia’s operation routes, so they sent out the one guy with the most experience. End of.
Mumbai: Again piracy, debt slavery, Eastern terrorism and racketeering are all crimes, terrible crimes but they aren’t the reason they died. Providence wanted the next in line gone and the ICA sent out 47.
Himmelstein: Again this is a criminal underworld contract. You are working at the behest of an accomplished career criminal to help him to his lost millions.
Port of Singapore: A government contract aimed at stopping an international incident and it is the only time the ICA align with the inherently noble goal of the mission aside from Patient Zero because if there is no one left to kill that would be quite the bummer.
Siberia: Again the ICA were paid to shut down a prison committing human rights abuses. Someone paid the ICA to do it and they paid enough for them to sent 47 out to Siberia’s ass.
Every other mission (WC, Sgail, New York, Haven) isn’t an ICA sanctioned operation (save for Whittleton Creek which was instigated on false information) but Grey seems fixated on tearing down Providence and it is his sole motivation with the fact that they are bad people even if they weren’t Providence being incidental to him.
In fact Haven treats their targets as obstacles that need to be killed rather than saying their identity falsification business is bad. As is Savalas and her illegal banking schemes and general mismanagement. She was also another random obstacle to the plan and she needed to go.
And of course that isn’t getting started with the other games especially 2 which devolves into a “47 you need to save the world” plotline by the end with IO being so stupid and greedy the UN has to browbeat them to stop nuclear Armageddon.
And who can forget Blood Money a game whose final official mission has a briefing that begins with “47, the president is about to be assassinated” and given 47 still has ICA resources I assume the ICA were in on it. All of this in order to stop the creating of a clone army.
