– Dr. Erskine: Schmidt must become that superior man.
– Steve Rogers: Did it make him stronger?
– Dr. Erskine: Yeah. But, there were other effects. The serum was not ready. But more important, the man. The serum amplifies everything that is inside. So, good becomes great. Bad becomes worse. This is why you were chosen. Because a strong man, who has known power all his life, will lose respect for that power. But a weak man knows the value of strength. And knows compassion.
– Steve Rogers: Thanks. I think

And a scripture to go along with it:

“And if men come unto me I will show unto them their weakness. I give unto men weakness that they may be humble; and my grace is sufficient for all men that humble themselves before me; for if they humble themselves before me, and have faith in me, then will I make weak things become strong unto them.” (Ether 12:27)
