When it comes to destruction and dragging others down to destruction, those who usually think about these problems are dangerous individuals with antisocial personality disorders. Normal people can't possibly ponder such questions, let alone implement them. But the battlefield is not a normal society; in the Shura Hell of killing and being killed, there was no luxury to consider morals and ethics. Especially for the soldiers who faced life-and-death situations daily—they knew no grand principles, only that if you wanted their life, fine, but don't expect me to stand there waiting for you to take it. When they knew there was no way out, their common thought was that killing one would break even, but killing two would earn one.
Therefore, when the iron turtles on the other side started to charge, the vast majority chose to fight to the death, even if it meant perishing together with the enemy.
Their feelings were understandable, and their thoughts were not problematic.
