The sets of lines are: "And remember Beauty, Five-Wits, Strength, and Discretion/They all at the last do Everyman forsake" and "For after death amends may no man make,/For then mercy and pity doth him forsake."
The key word in finding this answer is "forsake," which means "abandon." The doctor is listing several abstract ideas (beauty, strength, etc.) that forsake or abandon him "in the end" and "after death." If all these traits are abandoning him, then we can infer that the doctor must go on this last journey alone.
Tone is the author's attitude toward the speech. Since we know that Dr. King was the author and presenter of the speech, this was one of inspiration, seriousness, hope, and encouraging. This is not to be confused with mood. Mood is your feelings from the text. So, while the tone may be one of hope, to say it was 'hopeful' would be a mood (if that is indeed what you are feeling when hearing it.)
