Two things: You didn't find Adam mentioned in Gen 3:15. And secondly, you don't know the difference between comparisons and contrasts. And if Christ committed suicide then he is a sinner, since murder, as I seem to recall is verboten in scripture.
And where's the chapter and verse that "Adam sweat great drops in blood in the garden"? You are totally delusional.
And before you go celebrating your hero's life because he wasn't deceived as the Woman was, you should understand that that truth does NOT bode well for Adam for several reasons. The first one is that he sinned with his eyes wide open; he willfully sinned -- so much so that his sin is characterized as transgression (Rom 5:14), where Eve's is not. Secondly, arrogant and prideful Adam, who blamed God and the woman for his sin, never did acknowledge his sin before the Lord; for he hid his sin from the Lord (Job 31:33 per the most literal translations, e.g. KJV, Darby, YLT, NASB).
