Marcus seems to be between stages of identity development, according to this passage. For most of the passage, Marcus is in the stage of Identity Moratorium, as he is thinking about his views and opinions and what to do about them, since they are in conflict with Mr. Benson's, and may get him expelled. He considers speaking out, but also considers apologizing. Ultimately, Marcus ends the passage in the stage of Identity Achievement, because he determines, after weighing out his options, that his own values are what matter most to him.
Dear friend.
Imagine him receiving that message has been the only happiness in my life. I don't know you, nor do you know me, but if fate has allowed you to find my message, it's because you need to know about me and help, if not me, other victims like me.
I find myself trapped in the basement of the sadistic, mad, murderous General Zaroff. I arrived here after my ship wreck survived. I came in search of help, but I only received despair and panic. The general hunts me like an animal, plotting my death all the time. I can no longer sleep, and control my nerves, I live on the edge of insanity all the time and I believe that my days of life will be short if I remain here, or if I throw myself into the sea, trying in vain to escape my captivity.
I'm afraid of suffering at the hands of Zaroff, I'm afraid of a slow and painful death, but my biggest fear is that this rascal will get away with his actions.
Please take this letter to the authorities and help an unfortunate person like me.
