We do not know what made Kuma agree to have experiments done on him by WG .. its a mystery that only Vegapunk and Dragon knows .. .. but we do know what Law did to marines and it was not just some small thing. Helping to escape and heal WG's biggest enemy(in my opinion) was the last qualification WG is looking for in Shichibukai resumes. Well of course this is just my opinion and may differ from yours.
