In your opinion, is it OK to kill a spider, or a fly?
I'm sure everyone has done so at some stage and felt no guilt, or only just a fleeting moment of sadness at the life just ended. But, should we go out of our way to avoid the killing of other living things, even seemingly insignificant insects?
Can we allow ourselves this luxury on the basis that these are so much "lower" creatures as ourselves and therefore not worth bothering about?
I would appreciate your thoughts on this.
