Analysis of How clear the end!

Having lived life desperately seeking a purpose,
Now in my advanced years I have met it face to face!

Having thought the rule over life and death, now all is lost.
Forlorn, I look about to seek new heights from which to see.

Following others, I resist the temptation of death's door.
From my earliest memories come the death's of people.

Those who were famous or not, but who lost the desire to live.
Clearly now, ever so clearly I can see my end.

But cowardly, I shrink from it.
How clear the end!
