I actually own a revolver that was used as a hammer, and now it's a paperweight/conversation piece... so I guess it's still a tool.
The whole designed to kill business is just not true of many firearms. I shot NRA smallbore for years, and none of the rifles were designed to do anything but punch holes in targets. Have your friend have a look at some Olympic competition guns. They are tools like soccer balls are tools; you use them in a sport that teaches you muscular control, coordination, and most of all concentration. I was diagnosed as ADD as a kid, and I credit NRA smallbore rifle shooting with taming that pretty quickly; it was a brilliant tool. Just not for nails.
