No bad in the Paradise at all. Allah says in Quran about people in Paradise :ونزعنا ما في صدورهم من غِلّ (We shall remove from their chests all the hatred and make them real brothers). Sura 15, verse 47.
No one in Paradise thinks negatively nor has negative feelings whatsoever. No one will wish to do any wrong or even think to do any wrong as Allah has granted them the ability to see the right and wrong clearly so no one will ever want to do or think about doing wrong.
'Wassalam.
