I take your point. But the reason most people were expecting a more lenient ruling is because the full facts of what had gone on weren't known. Once the extent of his involvement became evident, I don't think there was ever any possible alternative to expulsion.
It's possible that a better legal team might have succeeded in avoiding that, on some kind of technicality perhaps. But it probably would have required an undertaking by the club to clean house and dismiss everyone involved. So even then, we'd have had no choice but to sack him anyway.
