I don't think Kano was either...savior or ruiner (is that a word?)...anyway, he was into athletics and developed a Jujutsu based art...Kodokan Judo. Judo should not really effect how one looks at Jujutsu, IMO. Jujutsu schools are still around...if that's what one is looking for...find Jujutsu. My opinion...after trying Ving Tsun, Praying Mantis Kung Fu, Bujinkan, Yoshinkan Aikido, Tang Soo Do, Tae Kwon Do, and Shotokan (very shortly with Shotokan), my honest opinions are that Judo is the best...for me. I honestly feel that if I got in a fight today..even though I have more Tang Soo Do experience than anything...I would rely mostly on my Judo. We train 'alive' and that is a great confidence/skill builder...just ask JKogas. I train with guys trying very hard to NOT let me throw them...and they are trained to defend. Against some average guy in a self-defense situation, or even a skilled fighter, I am very confident I can put them down with a lot of force. PrideFC is not real fighting, but it is pretty close...look up the names Yoshida and Fedor. They make it work against very skilled opponents more times than not...Yoshida is 4 wins/1 loss...the loss was to the current light heavyweight champ and it went the distance. Fedor is 14 wins/1 loss...the loss was to a TKO because the doctor stopped the fight for a cut. Bottom line, Kano did not necessarily hurt or help Jujutsu...but did a lot for a lot of people (including me), then and now, by developing Kodokan Judo (the sport based on Jujutsu).
