I have the exact same player. Cleric of Helm (and a Dwarf to boot, Life domain). Goes along with the halfling rogue where most plans are concerned.
I just let him get on with it. Although I occasionally make comments to the effect of "that's not really in line with your deity's teachings!" all that does is make him come up with some convoluted RP reason why the character acted in that manner.
I don't see the need to intervene. Helm is LN - do you penalise the player for persistently doing 'Good' deeds?
Just let the player have fun.
