Not really though. Catholicism is an institution with more power than a lot of countries, it used to even greater than what it is right now. Every other christian structure is directly influenced by the existence and power of the Catholic Church, whether they like it or not. Sure, it can be a force for bad and historically it has been even worse than this, like during the crusades during the sack of Constantinople, the debacle during the management of the reformation and so on and so forth, but it still is today a great force for good.
The influence of the catholic church on politics is what allows for example abortion to not be fully embraced by a lot of countries who's governments wish they could openly admit into their constitution (even if because of Francis' current way of talking makes it very blurry and has allowed some slips to happen).
If catholicism ceased suddenly to exist, other christians wouldn't benefit from it. Christianity would suddenly pass from the 1st religion in the world in terms of sheer numbers from the 2nd or third, and I think that atheists would benefit the most from it, followed by muslims. A lot of catholics and christians would be shaken because of this event and a great apostasy would follow. You're thinking too harshly too fast here.
