Yup i agree with u that thakurs deserve all this..
Firstly,they have'nt taught any sanskars to their sons instead they were taught to use riffiles,knife,hatiyaar etc..
Secondly,they never scolds shakti whenever he is tortchuring,forcing on sumone ..i think if they would have scold him from his childhood then he should'nt have dared to do this.
Thirdly,the always gave love to krishna ...this is kalyug and in dis era even brothers are fighting for da sake of properties or money ..da main reason is that parents are always showering their love to their most beloved child .which is leading to such differences..had sajjan loved or treated his both sons equally then it should'nt had happened.
