I'd assume the majority of people on this forum would be okay with killing a spider but not okay with killing a human (i hope ).
So if this is the case... "Why is a human's life 'better' than a spiders life?"
or is the question "is a human's life 'better' than a spiders?"
and after answering that is it then allright to squash a spider?
For those that don't know spiders do not have consciousness, they are virtually like arachnid machines with instincts.
Discuss away
I'll post my views after some healthy debate
