Sacrifices in all fates

[JaegrM]

The one which immedietly springs to mind are Mel's burning sacrifices for favorable winds to the wall.

We have Vic sacrificing the Maester for favorable winds, the Priest of the Red God Advises him to do so, but if memory serves it wasn't a burning or drowning.

Obviously these are both facilitated by Red Priests/Priestesses, even if not done in their.... burning-ish way

We also have reports from weight Harbor's.... Historian and other parties not connected to the old gods or R'hllor

Probably I'm missing other sacrifices- Still without my books

I'm under the impression that sacrifices do seem to hold weight in the world of aSoIaF.

But my question is.... are they legit pleasing to the deity's they worship? Coincidence?

Worshippers of R'hllor have the added advantage of being able to glimpse the future, so they could easily have the advantage of "good things ARE about to happen, I need to make these fools think it's my god's doing"

But Holy Trials by combat in the fate of the seven, fasting, etc.

All seem almost.... preordained? or close to it.

An argument could be made against The Red Viper vs The Mountain....

But Tyrion himself says something close to "I'm a naughty little imp and guilty of much, but I'm innocent of Joff's Death"

Possibly were the 7 punishing him for his other transgressions?
