Also, your logic here makes no sense whatsoever. Su'Kal's interaction with the dilithium did not alter his personality.
Su'Kal developed a connection with his surroundings; specifically, the planet's large
dilithium reserves. When he was approximately four years old, Su'Kal inadvertently caused
the Burn when he emitted a powerful psychic shockwave, which triggered the nearby dilithium. (
DIS: "
Su'Kal") The psychic scream was triggered by Su'Kal's trauma of seeing his mother's death.
Because of Su'kals connection to dilithium, his fear caused the Burn. Without the connection to dilithium, Su'kal wouldnt have have caused the Burn. Saru was going to Su'kal to the Kelpien homeworld and would have to eventually explain what Su'kal had done as a result of the interaction with dilithium, which would change his personality, tremendously, once he realized his voice took many lives.
The Klingons used to have a fire first and ask questions later warlike mentality. Klingons very rarely used diplomacy but always had the mentality of dying in battle as the only way to enter Stovokor. The warlike mentality can be seen in Kruge and the commander of the Klingon bird-of-prey from ST:V.
But after the loss of Praxis the Klingons toned their retoric down a few notches and became diplomatic instead of de-cloaking and opening fire. The reason being is that warlike culture of the Klingons had long forgotten the technology that had built their space culture.
Losing Praxis would have severly limited the Klingons ability to compete in unbriddled warfare between Klingon houses. Instead the Klingons would have returned to a more scientific approach to keep the Klingon houses from dying out entirely as well as upgrading their technology in order to be competitively defensive.
To be honest, it’s not entirely clear, and that’s partly because the show views Klingon culture from an outside perspective. In TNG, we see hints that Klingon scientists are undervalued by the front-line soldiers, while the Enterprise episode “Judgment”—the one covering the Klingon-human genetic virus—goes a little further. It suggests that Klingons have become so entrenched in their warrior traditions, they’ve begun to stagnate in terms of technological development—which could explain why humans were able to catch up with them in the space race.
Spock: Good morning. Two months ago, a Federation starship monitored an explosion on the Klingon moon, Praxis. We believed it was caused by overmining and insufficient safety precautions. The moon's decimation means a deadly pollution of their ozone. They will have depleted their supply of oxygen in approximately 50 Earth-years. Due to their enormous military budget, the Klingon economy does not have the resources with which to combat this catastrophe.
Having such an enormous military budget and losing their key energy production facility of Praxis, would have out the Klingon's on a limited budget for 50 years. In those 50 years the, Klingon's could have either continued to be extremely warlike or return to a less warlike nature but being defensively warlike to keep pace with other races.
