Once my temper got the best of me and using Aikido techniques I failed the "spirit" of Aikido by hurting the Uke more than was needed. On the other hand That has happened a few times actually... and usually starts with something like F**K You Aikido is for P***ies" or "Aikido does not work against THIS!!!" Followed by an application of Iriminage or Atemi...followed again by "Hey!!! Thats not Aikido!"
If I truely had the spirit of Aikido under these circumstances I would not have lost my temper.
