I know you are already yawning.. So I will tell you.
I daily kill few live cockroaches in my house, live spiders in my room with my chappal and dispose their dead bodies out of the house.
About dissection in lab, In lab i cut live earthworms.I dissected dead cockroaches which they provided to us in a tray and I pinned their dead bodies to the card board by wings. In Anatomy dissection hall, I dissected a cadaver(human dead body preserved with formalin).
And I cut open live human body or skin ofcourse not to kill.
