Did king Solomon die faithful or did he worship other gods in the end?

MY VIEW:

It is true that Solomon worshipped other gods, but if you will read the Book of Ecclesiastes, which was written toward the end of his live and keep in mind the Vanity that he continually speaks of and especially his summation in chapter 12, verse 13-14 it seems quite probable that Solomon fully returned to the LORD.

Ecclesiastes 12:13-14, " Let us hear the conclusion of the whole matter: Fear God and keep His commandments, for this is man's all. For God will bring every work into judgment, including every secret thing, whether good or bad."

Solomon was the wisest man on earth and if you count God's wisdom over man's wisdom you can dare say the wisest man ever. Solomon's desire was to use his wisdom to investigate all avenues of life including the worship of other gods and he found out that all is vanity and grasping for the wind.

Jewish view:

According to the Talmud (Shabbat 56b), Solomon did not personally worship other gods. Rather, he didn't restrain his wives from doing so. He had wives who had converted from other (polytheistic) nations and, when he grew old, he wasn't energetic enough in supervising their households.

Following in the prophetic system of castigation, he is criticised (1 kings ch.11) as if he himself had gone astray.
