The West is responsible for what has been happening to the Rohingya, more specifically the British whose divide and rule ethnic policies purposely and strategically inflamed ethnic tensions while they were the dominant colonial power, and when they were forced to leave they knowingly left behind political and border situations that were akin to time bombs that were guaranteed to erupt into ethnic conflicts all over the world, from Africa to South East Asia.

I'm not excusing the perpetrators, but i think we should be aware of the larger historical context. Such things don't happen in a vacuum and there are larger forces at work that benefit from continuing to fuel such conflicts and destabilization, especially in such a geopolitically important region.
