Red Angel didn't cause the Burn. The Discovery jumped forward in time to avoid the Sphere Data from falling into the hands of anyone while Red Angel was sent into a black hole and destroyed, supposedly. Unless Red Angel had some transmorphic interaction with the black hole turning the black hole into a time wormhole that sent Red Angel to the 32nd century, the Burn is somehow tied to Michael herself as well as being tied to Su'Kal. Ever since Burnham has been allowed back in Star Fleet her presence has done nothing but cause destruction. Just like the Song of Su'Kal nearly destroyed the Discovery, the Essence of Burnham has once again brought destruction to the Federation. But unlike before, Burnham can't run away. She and Su'Kal must face their fears or what ever is causing the central problem that is keeping both of their essences releasing deadly causalities across the Universe in no matter what time line they are in. Perhaps the death of Burnham and Su'Kal is the end game that will lift the veil to the true Su'Kal being born who will repair the damage that has been done.
No one got it because you're reaching. Grogu is still actually very much a toddler and behaves like one. Su'kal is clearly an adult who is both socially and mentally maladjusted due to having no proper social interaction his entire life. The source of their powers and their powers themselves are totally different. I could go on. What you're pointing out is nothing but bare superficialities with no substance.
Amusingly the Red Angel did cause the Burn. It caused the EMP, which knocked out the Ba'u technology, which freed the Kelpians, which a thousand years later resulted in the whole psychic super kelpian that caused all Dilithium to go boom.
We need to reset. Can we come back in time and take the time suite before Burnham mom use it to save Burnham? So we will have all in the right place again. No? Ok, so let´s just call Disco another alternative timeline... maybe the "Crying timeline"? And wait for the Pike show to be something better and in the "right" timeline, where the Disco events never happened.
