That’s true, og baby dragon was killed by humans in the original story but right now, we can see that it’s the world trying to kill him or something. Like how perfectly strong stable wood manages to crumble and almost kill him or the lightning striking him 100 times. (Hopefully this much info isn’t spoiling anything)

I think he meant that his past life he was terminally-ill which he died due to the disease. In his dragon new life, someone trying to kill him is like his past life. Meaning that someone is like the disease, which is why he said terminally-ill. He not ill, he just used that word to describe his past life.
Just asking, why does the fact someone wants to kill him makes him terminally ill?...
