I actually voted Other, simply because in realm of RP it tends to be a toss up depending on which member of either caste you come across, each caste has its strong people and its weak people. Both have a strict code that they should live by, both suffer thru betrayal and death, and both are a challenge to play to the true depth of the character. Merely strapping on a blade and wearing black or scarlet does not make you of either caste.
Of course I side more with the Scarlet though as that is what I am and have that bias. As Adoveea mentioned a Scarlet has to think about the greater good of his homestone, to put that above his personal motivations, and to need to consider every man that enters their city as to which one will create an issue. I will have to agree that many warriors today tend to indulge in slaves and drinks more often than their duty, but I have also come across 'assassins' that have no issue doing the same or taking gold from target to reverse a contract.
