As history has already shown during the Nuremberg Trials, "Following orders" doesn't absolve the individual responsibility of the people under command.

Spying on political enemies and arresting citizens? That's completely outside of their statutory powers.

But they aren’t following the constitution or the rule of law, hence rogue.

A core principle of a free democratic society is that everyone has obligations to more than the whims of a wannabe fascist dictator. ICE agents who do things like violently assault peaceful citizens are in the wrong, both morally and legally. The fact that the current president wants to destroy the pillars of our society means there won't be immediate consequences for that kind of behavior, but that doesn't make it any less despicable or immunize them against future consequences.
