You have problems. First, you shouldn't be shoulder bumping anyone. If you train to fight you train to avoid fighting. You suck for doing that.
Second, if you ARE going to shoulder bump someone, the headbutt should follow then repeated kicks to the head of what is now your downed opponent. The only reason to start a fight is so you can end it.
Third, you shouldn't be shoulder bumping people. I think I said that already, but you shouldn't be starting fights. The difference between you and that guy is that when he talked shit he backed it up, you puffed up your ego with your gym time then cowered away from a fight you never should have started in the first place.
Fourth, before you go developing your "killer instinct" develop your discipline and stop thinking it's cool to street fight.
Ya I agree with that too, but I dont think it has to be too the point of being attacked with a knife, mobbed, or basically the other kid throwing the first punch or something...ive seen alot of kids who take this as the rule and then seek to prove themselves with streefighting under that ruleset..they simply run around acting like douchebags and forcing people to stand up and fight them or be humiliated.
I like to think of myself as a really nice guy but this one time a stranger and his buddies insulted me. I was fine with that, not enough to start a fight over. Basically they mocked me for not drinking beer on the night as they started to crack open some drinks (i wasnt in the mood to drink taht was all). They were like 22 and I was 18, there was 5 of them..and i was just with my family. They then proceded to mock my dad calling him an old fuck when he defended me, this set me off since its family, when my mom said he was being rude he called her a fucking bitch. No lies I swear too god..this is probably the biggest douchebag I have ever come across.
He had just cracked open his first beer of the night. I snapped and went for him but was held back by the fam..alittle bit later on in the night he was in the clear, he then targeted my dad again calling him an old fuck infront of everyone..i thought my dad might react so I knew that I couldent let that happen since he could get hurt..also I was really angry, I kinda went snakey and by the time I got to him I calmed down completely and was just smiling and focused and he threw a shot and I dropped him.
Fighting outside of the ring imo shouldent be about your pride, it should be about defending people who cant defend themselves..whether they are being picked on with words or fists it doesnt matter. Especially family. the only other fights i had been in up untill this point were when I was 5 and 7. At 5 I was too young too really have any philosophy on anything and I chased down and beat this kid running from me at my fence gate after he had stole my toy. At 7 I understood better and a giant older kid punched my little brother in the face when i was around the corner at some place and when I was informed i proceeded to duke it out with him little kid style lol.
Any time I was just sticking up for myself nothing ever happened, I always used words. But family is the exception imo and no matter what i thought really I could never help it anyways I simply go into kill mode when someone fucks with my family and ALWAYS will.
lol
(I was fucking angry as hell before defending my brother and later in life my entire fam but after training and second time around I didnt fight angry I was super calm.
As for the guy your scolding, he was just standing up for his friend, a noble cause. By his reaction it seems he knows pretty well that fighting needs alittle more justification than this. He was bluffing when he bumped the guy and didnt expect a reaction. Doesnt make him a bad guy or evil.
Also when you think of all the best fighters or just all fighters in general..they scrapped a ton on the streets at the drop of a dime most of them...I mean GSP the best guy of all fought ALL the time. It is pretty ridiculous to ask someone to not use some of the skills they work so hard for if a douche bag comes along and is super obnoxious. People who are trained who run around being obnoxious to start fights and prove themselves..they are the scum.
Ok now for the actual threadstarter, you simply might be like me. In sparring I am weary to hurt someone as no one wants to hurt someone in sparring, when I was in these situations I had no problem finishing trust me (when it was done it was done though not saying i hit the guy out cold but when he was finished I walked away), now if your planning on competeing I have no experience there but I assume u are less angry but want it even more since you have trained so hard, therefore you will want it badly. Maybe you are born either born with a killer instinct or not I dunno if thats true but if you dont have killer instinct it sparring I believe it means NOTHING, infact it could be a good thing, maybe you are confident enough to not have to wail on your sparring partner to build yourself up. Trust me I am kinda at the same spot as you only ive been pushed into a situation that showed me I had killer instinct and you havent. If I hadnt have had that wacky experience I would probably think the same thing as you perhaps..when I step into a ring I think it will be the same. Chin up man your fine lol! and your probably quite skilled after a couple years training!
