It was a bit weird that they were remembering his words as they were rebelling against him right now, but that was a side of human nature after all.
Humans tend to do whatever befits their interests, everything is perfect, and just as long as things are going their way.
The same thing was happening with these guys, they were all feeling really righteous, and pleased that they were rebelling right now, thinking they were taking back justice for their selves.
As they totally forgot that right now they were biting on the hand that fed them when they were in their most dire straits. If you think about it, even a dog doesn't bite the hand that feeds him.
And yet these guys were able to do it with such a face of righteousness if Tianlong Yun were alive right now most probably he would have all turned them into experimental subjects.
