Is multiple sclerosis fatal?

Not usually: Ms is a chronic neurological condition, characterized by episodes of neurological disability of variable severity and recovery. A minority of inidividuals can have a very aggressive course, and become so disabled that they are at risk of secondary medical complications which may be fatal. There are subtypes of MS which are so aggressive that a fatal outcome can happen. Fortunately these are rare.

Most: As short as it sounds...We all die from something. It would be more common than not for people with ms to die from complications resulting from having ms...Whether the inability to have healthy levels of activity lead to weight/cardiovascular issues, or whether due to recurrent utis/immobility causing pneumonia/ulcer issues in more advanced cases, there is slight shorter life expectancy.

Mostly not so: Studies on pts taking disease modifying agents suggest that normal life span is possible, but if no treatment, life is shortened between 7-14 yrs. There is a deadly form, called Marburg, which is an aggressive downhill course in children, but is quite rare.
