If Magru Teller had not wanted to investigate Menilman behind the scenes, or forcefully made Charles betray his senior, no one could have shaken his position. He could have stayed comfortably as a warden in his cushy job.
Charles, too, did not understand why people in this world always employ unscrupulous means to climb the ladder of success. What's worse, they only see the potential benefits and never consider how dire the backlash could be once they faced retribution.
Magru Teller did not come from a prominent background, and if the former warden had even slight backing, he wouldn't have been helpless after losing power, nor would he have been tormented so badly by several army wardens. How much had he sacrificed and suffered to climb to the position of warden at Kilmainham Prison? Now that his family was ruined and he himself destroyed, it was as hateful as it was pitiful and lamentable.
