[Halloween/Friday the 13th.] Are Micheal and Jason actually serial killers?

I mean they don't have any long cooling off periods and rather just kill several people usually in the span of a single day. 

So would it be more accurate to call Micheal Myers and Jason Voorhees spree killers or mass murderers instead?

Perhaps ‘spree killer’ would be more accurate although, if we’re taking sequels into account, Michael Myers does have several extended periods of inactivity. *But* depending on which continuity you’re looking at, these periods of inactivity are due to extended incarceration/hospitalisation/magical coma. 

Friday 13th parts 2 - 4 take place in the span of a few days so perhaps spree killer is an apt description of Jason here. When Jason is inactive, it’s usually because he’s dead, or in hell, or cryogenically frozen.
