You might find killing spiders to be therapeutic if you don't like them. Find a mother spider and lure her spawn into a pool of water, great stuff! However, if you RELAY don't want them around, you would have to either mod the enemy to remove all the spider bits, or edit the maps and just get rid of all the spiders.

what should I do?

well...

map editing is covered fairly extensively on YouTube.

art file editing tools can be found here:

or you could just launch with the -nodudes switch and turn off all the enemies in the game...
