See, a key part of my arguments is that, while Ranald is a god of those things, he is not the only god of those things, as several more unsavoury gods for criminals exist. Ranald , imho, represents the noble and well intentioned parts of skulldudgery, which is why he is somewhat accepted while other criminal gods aren't, even though they are not chaos gods.
But, again, I do agree that there are at least 4 (ironic, lol) major interpretations of Ranald, each containing many minor ones on the finer details, the whys and hows:
The evil mafia don
The neutral thrillseeker/trickster
The good Robin Hood
The agnostic warp entity.
And if people propose there being more, I wont be suprised.
