In the eyes of God, they are the same, because the difference between the person who is willing to steal a paper clip and the person who is willing to steal a person's life is courage: a coward will only steal a little thing.
The question that most people are concerned with is not whether all sins are equal, but whether the societal effects of all sins are equal, and the answer is that the effects are evidently not equal. The law reflects this, because its punishments are not equal. God's grace, however, is greater than our sin--any sin--but His redemption is necessary for our sin, regardless of the effect of the sin upon (transitory, bound to eventually perish) society.
While it is true that it takes more courage to rob a bank than to steal a paper clip there are other sins involved in the bank robbery. The person who steals a paper clip sees it as no big deal, nobody will miss it, it won’t cause any harm. The armed bank robber callously terrifies people possibly making them think they are going to die in the next moment. Some people are even emotionally scarred for life. The bank robber then is commiting the sin of selfish lack of compassion. The same would hold true of someone who cons another out of their life savings. Not only are they harming that person but all of their loved ones too.
Yes, big crime takes courage, it also takes cruelty.
