SB 9.16.9

ye ’rjunasya suta rajan
 smarantah sva-pitur vadham
rama-virya-parabhuta
 lebhire sarma na kvacit
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear King Pariksit, the sons of Kartaviryarjuna, who were defeated by the superior strength of Parasurama, never achieved happiness, for they always remembered the killing of their father.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Jamadagni was certainly very powerful due to his austerities, but because of a slight offense by his poor wife, Renuka, he ordered that she be killed. This certainly was a sinful act, and therefore Jamadagni was killed by the sons of Kartaviryarjuna, as described herein. Lord Parasurama was also infected by sin because of killing Kartaviryarjuna, although this was not very offensive. Therefore, whether one be Kartaviryarjuna, Lord Parasurama, Jamadagni or whoever one may be, one must act very cautiously and sagaciously; otherwise one must suffer the results of sinful activities. This is the lesson we receive from Vedic literature.
