The Philosophy of Half Life 2

Half Life 2 probably has the most in-depth villain of any story, Dr. Breen: an entire philosophy was put into explaining why he would defect to the Combine, making the Earth one of their colonies. He reflects the same kind of sentiment that a leader of former colony might've had for their colonizers. It's an empire that cannot abide by limits and wants progress no matter the cost. Its intentions are good: it wants to unite all sentient beings in the galaxy into one Singularity. But just as every colonizer ever, it gets ahead of itself, letting the end justify the means. It's too hasty and throws caution into the wind, and if it would reach its Singularity, it would be an abomination.
