Is Tecteun the worst creature in the universe?

Her endless desire for power, as seen in the Flux episodes, combined with the fact that when her adopted child survived an accident. She started experimenting on ,and apparently repeatedly murdering, her own child multiple times to obtain immortality for herself.
Add to that the idea that Division apparently chose the species in the universe that should grow.
And apparently liked species like the Daleks/Kaleds(That is conjecture on my part)

Am I missing something worse?
