This is what
2 For thou didst not give so much heed unto my words as did thy brother, among the people of the Zoramites. Now this is what I have against thee; thou didst go on unto boasting in thy strength and thy wisdom.
3 And this is not all, my son. Thou didst do that which was grievous unto me; for thou didst forsake the ministry, and did go over into the

4 Yea, she did steal away the hearts of many; but this was no excuse for thee, my son. Thou shouldst have tended to the ministry wherewith thou wast entrusted.
5 Know ye not, my son, that these things are an abomination in the sight of the Lord; yea, most abominable above all sins save it be the shedding of innocent blood or denying the Holy Ghost?
13 . . . that ye lead away the hearts of no more to do wickedly . . .
So, Corinaton did all of the following:
A) Boasted in his own strength, thus denying God and God's place in his ministry (seriously not good - of the highest order, almost);
B) Forsook his ministry (seriously not good - right up there in seriousness);
C) Consorted with a harlot - while serving as a missionary (seriously not good - pretty high up on the list of sexual sins, given his calling at the time);
D) Led others away from the Church of his father and caused them to sin and "do wickedly" (seriously not good).
Alma said, "THESE things are an abomination" - not "THIS thing".
[It is important to note that, as far as we know, the "worst" sexual sin Corianton probably committed was "fornication" - since we have no indication that he was married at the time of the mission in question. He might have been, but that is not specified anywhere in the account. Further, since all we actually have in the record is that he went after a harlot, we don't even know for sure that he committed fornication. Also, Jesus is quoted as having taught that the abuse of children is so serious that it would be better for an abuser to have never been born than to commit such a sin. Finally, in our own day, there is a clear distinction made between the "seriousness" of fornication and of adultery - so it's not even fair to say that Corianton was guilty of the "worst" sexual sin in the account recorded in Alma 39.]
Remember, this is
In fact, as Andy pointed out in one of the comments on this thread, Alma 36:14 explains how Alma felt about his own actions:
Yea, and I had murdered many of his children, or rather led them away unto destruction; yea, and in fine so great had been my iniquities, that the very thought of coming into the presence of my God did rack my soul with inexpressible horror.
I don't believe it was sexual sin that
I think that is critical, and it gets overlooked when most people read the account without parsing the actual words carefully.
