Morote-Gari is the Karate double leg takedown. Such technique may be performed in Kumite but itβs dangerous because by lowering your leg you expose your head to kicks. In the self defense, itβs usually best not to perform throws, because of their complexity (that under stress you hardly manage to handle) and for the damage that you could cause to the attacker (you are not on a tatami mattress, depending on how the aggressor bumps his head could lead to sever injury or even death)
