Poisoned is much more useful than Keymaster. Plant a paralysis poison on someone will guarantee you a 100% success rate when it comes to pickpocketing, so you can also move four of those perks to something else instead, like Light Armor, considering you'll have very little defense if you're dual-wielding. Lockpicking perks are useless in general, as are the Axe/Mace/Sword specialty parts of the One Handed perk tree.
If you're character's so righteous the perks on the right side of the Speech skill tree are largely pointless, since you won't really need to bribe or intimidate people (And why do you need to steal if you're "righteous?") Also, you don't really need to lower the prices of anything, since money is literally no issue in this game.
