The UK has just concluded its investigation into “steakknife” - an IRA killer who was also working for British army and killed people on both sides seemingly with impunity.

I am guessing there is a mental hurdle in committing larger and larger crimes, but having “permission” from a government spy agency probably makes such things easier.

It’s ok to commit this crime - I have permission so it’s not really a crime.

The point is, no-one sees themselves as the bad guy.
