Karma question!!?

So i been pending the idea of goign to work out... jogging 3 miles outside. ITs 12:17 AM right now and it raining and a little bit of lightning. I want to jog but i believe in karma. I beleive once somthing good happens to you somthing bad is followed by it. I just got paid.. and when i got home i killed a giant moth in my house that was flying around.and i believe if i go jog outside somthing bad will happen to me due to karma. Like get struck by lightning or someone will shoot me or somthing! Should i just shut the eff up and go jog or should i not jog because of the bad vibe i get from karma
