ok, i just realized what the ending means. some people may think, Philip betrayed the tuurngate, and that he is a plain ass. i think the opposite is true. he is almost a martyr if you think about it. he said he would not make the same mistake as his father. the thing is, his father sent him a letter, to destroy all evidence of the base, just like Philip was told to do by the hive mind. but the thing he realized, and the hive mind knew it as well, is that Philip is not like other humans. Philip is at first, but as he ventured deeper into the cave, he changed. when he got the letter, he did what anyone would have done, he went and investigated, he gave in to human nature. because of that, he discovered a secret that no one would ever want to know. just like his father, he passes the tests, and was given the job to make sure the base never existed. but look at what happened, Philip got the letter, and he went to investigate, its human nature, we cant help it. if he was to send a message out, and tell someone to destroy the evidence, whats to say that they would not make the same mistake he did.... remember... "do not make the same mistake i did". and even if they were to not make the same mistake, what is to say that the cave would not be found out again. and human nature would repeat itself. Philip new this. and what would be the only way to prevent that from ever happening? to destroy everything, Tuurngate included. its not because he is an asshole. he is the opposite, he did what was best for mankind. because if the tuurngate dosent exist, it cant ever be tampered with because humans are the ones that released it, and if he just buries it, what if they dig it back up again. he is almost a god in my eyes, he died so that all of us could live, and no more lives would be lost.
