The man who killed his wife’s attacker after stabbing him over 20 times has cited financial hardship as grounds to give up on his appeal over his life sentence. Tian Renxin saw red after coming to the rescue of his screaming wife and discovering she had been raped by workmate Zhang Ping at her work dormitory in Zhejiang. Picking up a bottle, Tian disarmed the knife-wielding Zhang and then turned the blade on him. Tian lost faith in his appeal after others told him that without money it will be futile. With car killers getting 7 years, one netizen blamed his whole predicament on being poor.
