There are many historical instances of former "heroes" turned traitors being allowed to off themselves, rather than go through trials or courts martial, as an honor of their prior service, and to spare the tarnishing of the institutions of their prior service.
These latest Q drops hinting of MI authority over the 3-letter agencies in a special case of a coup attempt using and abusing all the powers of the intelligence agencies, plotting nuclear war against the citizens of the USA, etc., etc. -- these are crimes that scream out for the death penalty.
For these traitors, suicide would be and should be the easy way out. Otherwise, the trials and executions should be very public and eternally damning.
Great scene in Godfather II with Pentangeles comes to mind.
Tom Hagen and Pentangeles talking Rome, the good old days, and smoking a fine cigar.
Excellent.
