The Manchester City striker, who moved to Eastlands in the summer, is facing the possibility of an extended ban after being at the centre of two controversial incidents during Saturday's 4-2 Premier League win over his former club.
"My thought is that Emmanuel Adebayor deserves to be charged for what he did," reflected Wenger as he spoke to the media ahead of Wednesday night's Champions League Group H opener against Standard Liege in Belgium.
"That is why I was deeply surprised and shocked."
The Gunners boss continued: "Only he can say if he will regret leaving.
"All I can say is that is life and professional football players move on.
"In life, the goal is to be objective enough in seeing who helped you and who didn't help you, who had a positive influence on you or not.
"You can sometimes be disappointed in the short term.
"But still I believe that when you take distance with the events, you always get to the right judgement.
"I think the longer distance will make Adebayor realise that Arsenal was a very positive influence in his life."
