D&C 137

As the Prophet Joseph Smith saw in vision the celestial kingdom, he saw individuals there that somewhat surprised him including his brother. In answer to his thoughts, the Lord said -

"...I, the Lord, will judge all men according to their works, according to the desire of their hearts." (Doctrine and Covenants | Section 137:9)

In my mind, that verse suggests that there are many and great variances in the weaknesses and conditions of men. It is not black and white. The Lord is saying that individuals will be judged according to their works - according to the desires of their hearts. In other words, the capacity and God given weaknesses of each individual will be considered in the great judgement. We need to be careful then how we judge.
