Your first stanza was much stronger than the second. Also, the "Just" detracts from the strength of your words in the last line. I find that if stanzas are similar in length, poems flow better... but that's a matter of opinion. The "great" is another detractor. Both of the words I mentioned seem like fillers... or the way one might speak. We use so many fillers when we speak! It's better to keep them out in writing. Too much emphasis actually takes away the power of your meaning.
Now I see the style is Sedoka - missed that before. Ah, well in that case, I think the syllable count was necessary? Still, I would recommend different word usage.
For Example:

Many chase the dream
Their hearts eager to an end;
Racing toward certain death.

It's your poem so you keep it however you see fit!

:) Overall, a good write and the beginning captured my attention.
Well done.
