You have to be careful about blanket statements like "INTJs don't rob banks" or "he hated authority therefore not SJ". Try to take things in a context.
Stalin's father was an abusive alcoholic who couldn't hold a job, and Stalin grew up in lawless country. These kind of surroundings can be viewed as a lack of proper authority in the SJs eyes, resulting in the disdain of such environment, not a hatred toward authority in general.
Stalin's own way of running the country was through extreme micromanagement, which is not exactly a way someone who resents authority would operate.
I did not made that uip Edgar, I read it somewjere in a book, although i could not find the sourve.
Stalin hated authority because his father beated him often, and this transformed to a general hatred towards anyone that yields power over him.
Although i agree with your point of Sj disdain of the enviroment, to say that stalin is a ESTJ just because he exhibits Te in his dictartorship is too vague.
Anyone running a country would need some sort of Te to maintain order,
Stain is aq complex character, and his machieveillian tendencies does not correspond to SJness.
The hardest thing to put into perspective is whether stalin is a J or a P. His plotting to remove trosky has demonstrated amazing flexibity and calculated planning, this seemed not very J.
Furthermore,. his admiration for Koba ( a ficitional russsian outcast like robinhood) also seem unJi, as Js favor order chaos. Stain seems like one who follows his own code of rules trather than the rules of socirety.
