These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Crowning Moment of Heartwarming: There is one, in the fifth volume, Seu has been revived and when he wakes up, it's implied that his brain is being retarded every time he heals. If you look at Mensab and how she cares for him, you realize that he's the only human she would ever give a damn about, like a mother.
Designated Hero: While he certainly comes off as this, it's debatable whether Killy really is one, especially since we see so little of his thinking. In a charitable interpretation, he is the only person seriously trying to make the setting a better place.
The Silicon Life start out attempting to destroy all traces of the Net Terminal Genes and forever seal humanity from the Netsphere - but by the time Blame 2 takes place, the new generation of Synthetic Life are being hunted down and simply want to be left in peace.
The Safeguard was originally set up to keep unauthorized users like Silicon Creatures from logging onto the netsphere and screwing things up by killing them. Now due to a combination of programming decay and desperation they usually just kill everyone everywhere and hope that things will work out.
