Here's my take on this; yes, what Japan did was very horrible but that is what invaders do. The way they killed people is equally atrocious but you have to understand that Japanese people are not normal; when they kill you they make sure it is in the more gruesome way as possible.
Japan must be taken care of in the future we cannot forget that but we also cannot forget what the British did. What they did was even more worst IMO because their actions were not actions based on war adrenaline, rather a very calm and heinous approach by sneaking drugs into China and trying to get the entire country addicted to opium.
And when Chinese tried to ban this drug, the British fought a war to allow it to thrive. I think there is way too much Japanese hatred. Hating Japan is right but we should not focus all on Japan.
Britain should be #1 on the list followed by Japan.
In these modern times, it seems Britain has been very quiet, almost like simple bystanders watching global events but there is no doubt that Britain still controls the United States and uses the US to continue the British Empire.
We all know the US/China rivalry and how they continue their geopolitical strategy to contain and surround China. Don't look at this as US vs China. It is Britain vs China as it had been from days of the Opium war.
Britain is the #1 devil. US, Japan, India are all lackeys.
