Fragen über die Beispielsätze mit, und die Definition und Benutzung von "Cataclysmic"

A: placed us on (...this course) : to put (us) on, set us on this course
cataclysmic: "severely destructive"
ultimately: in the end

This course (path, route) will ultimately (at its end) result in his death.
>>>I feel that "course" is less literal here. I imagine a "course of destiny", where the end of the course (his destiny) will be to die. What caused that death, is XXX placing them on a "cataclysmic course".

A similar example sentence:
Bob's decision to drive in the snowstorm placed us on a course that would ultimately lead to a devastating car crash.
