To answer your question, Marlowe is a character who had a lot of righteous ambition and the readers were privy to ways in which he still had a lot of story left untold. Was Marlowe really going to rise through the ranks and make a difference in the world in time? We will never know now.

To put it another way, we knew Marlowe enough to have questions about him that will now remain permanently unanswered, such is the price of death, to put it bluntly.

And going to the titan serum and Zeke, I think you're thinking too far ahead, right now, Levi is on his last set of blades and the quad got a head start running away. As nice as it would be for Zeke to be a unique resource to save Erwin's life or someone else's life, Zeke might be a bit too elusive.
