ECL2: Krolor Druid, Necromancer

As I sit around seeing my lizard almost die I think to myself when I learn more about Necromancy I could kill my lizard and raise him from the dead and make him more powerful. How would I kill him? This bothers my mind the fact that i'm thinking about this. Maybe I could make my animal companion do it. Nope, i'll have to do it myself. There's no way I would make him do that, he would have to live with it for the rest of his life. It wouldn't really bug me to kill him it's just that i probably can't do it because i'm so weak. I could ask one of these stronger people that i'm following to do it. No that's crazy.
