Papa Wemba reacted badly but no,he's not a fool just like he said in his interview. Koffi has been proved to be the monster in the Congolese music industry, Koffi is everyone's enemy, even Werrason is slightly better but Koffi no,he's like a murderer, giving people plastic smiles and stabbing them in the back when they give him his back.
Papa Wemba,JB Mpiana, Werra, Wazekwa, Fally, Karmapa and all the big stars get along with each other or at least they are not enemies but they have one common enemy,Koffi!! So the fool is not Papa Wemba, it was an error of judgement for him to react that way but off course any of us would react if a mere greeting of ex-friends and colleagues or enemies was blown and headlines hit saying reconciliation yet there is no actual reconciliation.
