Chances of you being killed by worm are low but never zero!
the one grants you immortality at a touch, the other kills you instantly.
You can avoid this problem by cutting the worm lengthwise.
That makes it worse, actually. The half that doesn’t forgive you is the one that’s the asshole. If you cut it in half lengthwise then both of them get the asshole.
There’s a reason why someone invented the flamethrower… 😉
That’s why you should then cut the vengeful half again into halves, but unfortunately this goes on forever.
