As I understand it (first-hand info from one of the crew), they lost NW steering and had only enough directional control to get the aeroplane off the RET. It appears, although unfortunate, and inconvenient for many others, I believe the crew did the right thing and stopped it where they could.
Apparently it was either that, or go off the paved surface.
Bear in mind it was dark, and Dublin has possibly (IMHO) the crappiest taxiway lighting out of all north-western Europe's major airports.
Of course it's easy to misinterpret the written word, so i apologise if I've got the wrong end of the stick, but the tone of your comments seems to imply the crew were inconsiderate or not competent by halting it where they did.
As they say....(whoever they are), sometimes that's just the way the cookie crumbles.
