Sundering stuff established in the Q&A

[tokinokanatae]

You can see the obvious emotional disconnect between Emet and everyone else present when he smilingly exclaims that killing millions of sundered people doesn't really count as murder, because he views them all as 'malformed creatures'. He can read the room well enough to be aware that he's just said something very offensive from the awkward silence and shocked reactions, so he quickly changes the topic after, but he still doesn't actually seem to 'get' why his statement was so poorly received.

Ah yes, Emet-Selch, well known for his...emotional disconnect?

You additionally have Hythlodaeus describing Emet as a "slave to sentiment," and Ishikawa saying that what led to Emet's downfall was his kindness. Meanwhile, we have Venat acknowledging her actions had no kindness. Clearly, what we must take from this is that kindness and human feeling is for losers; ice-cold ruthlessness is the way to victory. (Joking! ...or am I?)

EDIT: Thinking about it, it's sort of oddly perfect that Emet-Selch tanks as a DRK and Venat tanks as a PLD, isn't it? The DRK questline establishes that being a DRK means being powered by emotions, the desire to protect your loved ones, and struggling with the internal conflict that results. PLD's questline is about single-mindedly chasing the abstract symbolization of an ideal that revolves around establishing one's strength over others.
