See, this is for very long discussion and its maybe worhty of opening a new thread about
Deity alignment = Character alignment > Yes or no?But the fact is that Helmites hierarchy is pretty militaristic and VERY strict. By not obeying the order you immediatelly find yourself on very thin ice which mostly ends by your removal from Helmite ranks. So yes, i see a huge conflict between LG and LN, especially in Helm's case.
Paladins are mainly diplomats and they are using violance as a final solution in most cases. They will offer peaceful solution once, twice etc etc...... before they lift the sword.
Helmites are more
soldiers, they are not to be messed with because of their strict nature. They offer you peaceful solution once and then you get shot.
Also, perfect book is this.
