Well, I hate to kill any living creature, but I think there is a time and place for everything, and perhaps this is a time where it is ok to kill animals. I try to live by taking as little life as neccesary, and eating meat is certainly not essential to my well-being. Squashing ants on a sidewalk is not neccesary to my well being. Having a roach/flea/tick/termite free home, however, I would consider neccesary, so I would do it.
However, I wouldn't curse the roaches for thier nature- they didn't choose to be roaches, they can't help thier appearence and way of living. They are trying to live, just like any creature, including you and I, are trying to survive.
Basically, I, personally, would exterminate them, and probably apoligize over and over, and feel pretty bad for it.
Ok, so I most likely qualify as 'strange.' Oh well.
