"Hahaha! Serves you right! Let's die together!"
"Dare to steal our car! The karma has come, hasn't it? I want to see how you are going to escape!"
"Escape? Just go to hell!"
Without a means of transportation, the survivors had no chance of escape. Fear of death spread within them, breeding resentment towards those who might be able to escape.
They had already witnessed what those silver-armored zombies were like; they couldn't be defeated, no matter how much you attacked. Even headshots wouldn't take them down. Essentially, they were undying beings. How could they hope to survive if such creatures got to them?
Impossible!
As they watched the silver-armored zombies on the convoy, they felt a perverse pleasure. Such warped human nature meant they couldn't bear to see anyone faring better than themselves. Since they were going to die anyway, why not drag a few others down with them?
