No, he was very bad. He was after Mobutu, the most hated guy in Kinshasa. He killed alot of people, he stole married women, he also liked to humilate and intimidate people. He didn't like to have handsome guys around him. If he saw a guy with looks near his table if he was visiting a concert at intercontinental, he would then send his guards to send that guy away. But for people working for Yoshad Production (Francis Kalombo, Zacharie Bababaswe, etc.), his soldiers of SARM "Service for Military Action and Intelligence" (which was made to stop and/or kill UDPS-supporters and opposants of Mobutu) and musicians like JB Mpiana, Werrason, Papa Wemba, Marie Paul, Blaise Bula, Manda Chante, etc. he was a hero. Because he was giving them alot of money with them giving big praises during concerts (l'Homme Fort, Tempete de Desert, etc.) or a song dedicated to him in return. With all bandleaders and musicians trying to be close to him and Yoshad Production, knowing that they would get alot of money from. It's just like how all musicians of DR Congo are trying to be close with the children of Sassou Nguesso (Claudia Sassou, Denis-Christel Sassou, etc.) these years.
Alot of people don't even know that JB Mpiana used Kongolo's Benz in the No Comment Schengen-videoclip and some parts of the Pentagone-videoclip were filmed at Kongolo's house (Coco Madimba, Pentagone-generique & Heritier Itele)
