Breen's unfortunately pretty underrated amongst the Valve antagonists, which I suppose is understandable compared to the likes of GLaDOS or The Administrator, but just like those two I feel like there's plenty of things to talk about when it comes to him. He seems like a very conflicted character, especially if you take into account the BreenGrub account and Laidlaw's Epistle 3.
First of all is, of course, the leadup to the Black Mesa incident, with the G-Man seemingly making an offer to Breen which seemingly involved overloading the Anti-Mass Spectrometer while processing an extremely pure sample of Xen Crystal - and yes, while it's pretty obvious that the order to overload the systems was very intentional and motivated by whatever deal they struck, I believe that when it comes to the aftermath he may have been sold on a lie. Considering his actions as Administrator of Earth being entirely in the interests of keeping Humanity from feeling the full force of the Combine, I don't think "Becoming the de facto leader of all of Earth" was on his agenda. Perhaps G-Man promised that whatever their deal would entail would bring about a prosperous future for humanity, perhaps all he promised was the possibility of establishing contact with another sentient species (which is something he technically did provide), or perhaps it was something else - there's simply way too much room for speculation there, I think.
A little detail from a HL:A newspaper implies that his position as Earth's administrator wasn't exactly handed to him on a silver platter, instead he had to go out of his way to reach out to the governments with information on how to communicate with the invaders, at which point, already beaten down by Combine forces, they simply gave him the all-clear to speak for all of mankind. This still begs the question of who, or what, gave him the knowledge of how to speak with them - however, it's safe to say if they didn't, Earth would've been left a smoldering pile of rocks and withered carcasses. Once again, he acts with Humanity's best interests in mind, having to choose between the lesser of two evils - it's either enslavement or extinction. He simply chose the option in which Humanity would survive, even if just for a little while longer.
And ever since, we're watching the aftermath. He's trying to talk the last generation of Humanity down, so they may either pass of old age or be absorbed into the Combine - at least if that happens, something gets preserved. Once again, the alternative? They'll just wipe the slate once they get the local teleportation technology they desire. Breen sees no other way than to go along with their demands. He's eventually proven wrong, of course, but he refuses to see the Rebellion as anything but a suicidal march towards the extinction of the human race, and he sticks to that belief up until he is killed by Gordon at the tip of the Citadel.
Of course, this doesn't make him a good person. Not at all. This belief has lead him to seek out and destroy anyone who tries to resist. He shows no sympathy to them. He paints them as fools. He himself believes it so. This intense hatred for anyone who resists is seen perfectly in how he treats the Vance family. He views them as fools. As narrow-minded rabble in the streets, senselessly struggling against a tide beyond their comprehension. He's willing to send off a father and his daughter into a world far beyond simply to use them as a bargaining chip. Listening to the two comfort eachother as they're almost raised up to a fate surely worse than death, the only expression on his face is that of pure contempt and annoyance.
He's a very fascinating character that I wish Valve would explore again if they ever do another Half Life set during a time period in which he was still alive. He's a coward that easily bends to the oppressor, yet in the end he only does it to make sure something survives. He's cruel to those who resist because he's completely convinced they're going to get everyone killed. He is the Combine's perfect puppet.
haha anyhoo so why was he straight up serving on the magazine covers in HL:A like what was up with all that
