There is some confusion, I believe in how God views sin. The Bible communicates that all sin carries the same penalty, but it does not imply that all sin is equal. Some sins are clearly portrayed as more agregious than others, sometimes called abominations, and one sin is portrayed as unforgiveable.
In this particular list, I believe wrath is the greatest, since wrath or anger is equated to murder by Jesus. Of course, pride, in some circumstance could be worse, as it could be an affront directed against the holiness of God, if we were to stand pridefully defiant against the Lord as Satan did.
On the other hand, that there are some sins more damning does nothing to make any other sin less sinful. Take sloth, for example. James wrote that the one who knows the good that he ought to do, but does not do it, for him it is sin.
To sin is to be a sinner, and that we could point to one who has done worse does nothing to cleanse us from our own transgressions.
