Should i feel bad? I used my Airsoft gun?

Don't feel bad because no one feels bad for you. I mean people in the UK have teeth that snaggle and start to fall out and turn yellow, well right about 13 years old. Guaranteed you will wear women's clothes sometime soon that's the British way. So you killed some defenseless animals that weren't hurting you maybe some nice Irish boy will do the same favor to you one day. Pip pip cheerio!
