When he started to weaken, he got more into his broken mentality (because the guy is actually just as broken as other capes cause his backstory)
Yes, his profile is that of a significantly broken person. Inferiority complex (his need to prove himself), narcissism (others feeling intimidated when talking to him), and possibly a couple of others. Many of the behaviours of people with a damaged psyche are unconscious and they actually don't realise that they're doing them (doesn't make them any less damaging though).
So, no, it wasn't his Shard doing what it thought he wanted - it was his Shard doing what it was told to do but that Eidolon didn't know he was doing.
It's worth pointing out here that the Shards read the hosts mind through the Corona Pollentia/Gemma and do what they interpret that the host is telling them to do. If Eidolon didn't want the Endbringers, as you assert, then they wouldn't have happened or they'd return to where they came from.
You're right I missed that last one where he fully called her out, probably because there was no reaction from Armsmaster about the reveal.
Was highly surprised that there
wasn't a reaction from Armsmaster with the reveal.
Wouldnt parahumans escalate to match? Cause if they start getting hunted like that they have very few reasons to hold back at all. Or start working together with other parahumans more making even more powerful groups.
Not really. That would already be happening even without the parahumans if it was going to happen. Cities would be ruled by The Mob/Yakuza/whatever is the local equivalent. Basically, we'd still be in a feudal error with each local lord battling against their neighbour for more land and serfs.
I really dont see how this ends up better than without Cauldron.
It ends up better because the villains are actually taken down
before the people are demanding such debilitating strikes rather than being given a free-pass due to
'Unwritten Rules' that only the
'Good Guys' (who's job is to actually investigate and capture the villains) obey.
If it were that easy to get rid of him after he's had time to collect muscle and hostages, someone would have done it.
Apparently,
it was that easy. A competent investigative team and a sniper from 2km should have had Heartbreaker in the ground within a few months of him Triggering.
