the only ones using their power to protect Humanity
Yeah. Say that to Mairaath. BTW are not they looks through fingers on those terroristic pathers, when it could give some benefits in shared enemy war? And here "when" is rather "always".
How are the TT good guys? Didn't they create the AIs that likely caused the Domain to collapse?
1. Domain collapse with gates collapse. Is it related to AI somehow - ask Alex, he keeps it in secret.
2. Even
if collapse is caused by AI - definitely not because AI made by TT. TT starts a massive AI production only
after collapse, because domain would never allow them do this before that point.
3. TT did not loose control of their AI before first war, TTDS was obedient and not "kill all humans" they became after. Who start that war? Hint: the Hegemony. Why? Because of fear not to be the only superpower in sector, as AI makes TT potentially stronger. Yeah, "lets kill a half of a sector, because we do not want to loose our influence".
How are the TT good guys? Well yeah, they are evil. Blatantly. But those "evil guys" keep on trying in science field to regain all loosed technologies, sector desperately need. Who know what will happen, if they was not
forced to use AIs in military to protect themselves in those wars with bastards, called themselves a law?
Greed and Gluttony is lesser sin, than Wrath and Pride. So, yeah, TT are less "bad guys" than hegs.
