Not saying they're necessarily evil. They do have a duty to warn and advise when a country is seemingly committing economic seppuke but I don't get the fear behind PK's move (if true). There are far bigger problems they need to solve on the ground. PK may have a power surplus but they need to fix their regional grids. Ask any Pakistani if they have ever went through an entire year without power cuts.
They are evil, and people who believe otherwise are very naive. They don't have a duty to create wealth for your country, they have a duty to create wealth for themselves.
I would say no more or less evil than the states that opress their people anyway. You can steer the economy any which way but the richest will benefit. Covid? Banking crisis? (hyper) Inflation? For most people, it's between people losing jobs, losing homes, considering suicide, or keeping status quo.
PK can go do what it wants with Bitcoin mining, or not. It will not change the life of the guy in the street. Fixing their grids so people don't sleep on the roofs in summer, that can change the guy's life.
