AM I BECOMING A SADIST?????????!!!!!!!!!!!

I am a 14 year old teenager who spend most of his time reading or on the internet.But I do go to judo lessons and go to the gym,I am non violent person,I only use violence if someone attacked me other than that I dont use my hands.But I do have an obsession with guns rifles swords grenade launchers tanks etc...I love reading about them.

I know that your getting bored So I will go straight into the subject.

lately I started loving to annoy my little baby cousins.Most of the time I am good with them but suddenly I start annoying them and making them cry and I love hearing them crying..There is a cat infront of our house that comes to the rubbish bin and eats whats inside it making a big mess but it is scared of water so I took a cup of water and start spilling on it and started chasing her down the neighbourhood,Inside me I want to spill water on her face and hear it screaming,I did try that but I always missed her DAMMIT.And in the comics that I draw 95 percent of it is pure gore.I sometimes wih if someone would come and fight me in school so I can make him suffer and choke him until he falls in a coma,Ofcourse I hide these ideas from my friends.And if I told them they will start laughing badly.

Plz can someone tell me WHATS HAPPENIING TO ME I DIDNT USED TO BE LIKE THIS,I WAS PEACEFUL,I LOVED TRANQUILITY BUT NOW,............AND NO VISIT A DOCTOR BULL****************************.

See what I meant I am becoming aggressive.
