Life Is Precious. Period.
I think that we all have a right and deserve to live. If I can carry it out, without it biting me, I will try, but I am scared of spiders. I think there are good reasons for this. I don't want to get poisoned, etc. I think it would be neat to have a pet spider someday, and confront my fear, such as a tarantula.
Now if a spider moves really fast, and it is in my room, I might kill it, for fear of it eventually biting me.
