Samson the Religious Man

In the Bible, there are all different kinds of broken people that God uses to His glory.  David was an adulterer and secondhand murderer, Abraham told his wife to marry another man to save himself, and even the "good" king Hezekiah was satisfied to know that his descendants would bear the brunt of God's wrath on earth instead of him.  All of these are distinctly flawed people, who are also in the kingly line that lead up to Jesus.
So what of Samson?  Why did God choose to make a strong man one of Israel's saviors?  I think I've stumbled across one reason.
In Jesus' teachings, those who blindly follow religious commands are harshly rebuked, and he gives a basic command that sums up the Law and the Prophets:  Love God, and love other people as much as yourself.  Some of the pharisees and other teachers (surely not all, as is evidenced by men like Nicodemus) became so caught up in being certain of petty details that they forgot God's larger purpose and overarching command.
Back to Samson; perhaps God chose to make a strong man to show that the weak and humble are more endearing to him.  Samson was given very specific instructions:  don't drink wine, don't cut the hair, and don't eat anything unclean.  Samson followed the instructions; and yet, for all his strength, he remained prideful and only used his God-given strength for personal revenge.
God used Samson to destroy many of the Philistines, but the victory could have been more complete if Samson hadn't become trapped into thinking that he was doing fine with the commands given to him.  He could have done so much more if his pride hadn't led him to think he was good enough.  He knew God and His power, but pursued only personal revenge as opposed to God's justice, right up to the very end of his life.
