How are implicit descriptions used to describe heroic or monstrous traits?

When an author introduces a character, he can use both implicit and explicit descriptions. Explicit descriptions detail the characteristics of a person, so that the reader does not need to reach his own conclusions about them. On the other hand, implicit descriptions are developed by describing a character's actions and thoughts and letting the reader reach his own conclusions. In the case of heroes and monsters, the author can use descriptions such as the need to help or the need to harm in order to develop these characters.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.

i would pick a. i think this is more of a personal question though.
