Yes you do; and the reason you fail at it because of your general inability to grasp the distinction between reality and fiction.
And you fail at it because of your general inability to grasp that as soon as the argument turns to meta fictional reasons it ceases to remain valid conversation. How can you say that "she murdered him in cold blood" if you are also to refute others' arguments be explaining "the author did it"? You turn the whole thing into a false equivalency where any argument against is wrong because of meta fictional terms that render in-story arguments invalid, while any you construct is right using both.
If one was to look at the facts in-story-
-While it is acknowledged that many do come back from the dead most characters still operate under the assumption that they won't, at very best not for a long time.
-Max Lord had killed thousands, possibly millions of people.
-Max Lord currently had one of the most dangerous weapons under his control at the time of death - Superman.
-Max Lord also has the power to affect many, many more even in his present state.
-Under the lasso, which reveal only the truth, Max Lord responds the only way to stop him is to "kill me".
-Wonder Woman, while a hero and an ambassador, is also a warrior.
-In the time that Max Lord has been gone, we've had dozens of Joker appearances, the same for Lex, Cheetah, etc.
And while you may be trying to argue something else entirely, your response to SuperFerret's belief in the death penalty - an extremely complex issue that most logical people recognise is a multi-faceted, highly subjective one - as apparent proof that he's kidding himself into wanting to watch "murdurz" says more about your own beliefs than your assessment of the WW incident, with the former perhaps colouring your perception of the latter.
I think I'm going to have to read t again, but I thought Superman WAS still under his control.
Wonder Woman had him tied up but Supes was still a factor, albeit not immediate. She asked Lord while the lasso was around him how he could be stopped and he said "Kill me".
I took that to mean there was no other way to break his hold on Superman and limit the damage short of killing him, so she did...
That is how I recall it as well. Supes was still under his control.
