Absolutely not; this is the worst thing that could happen at this point.
Aristide was a charismatic but divisive leader.
All he did was set the masses against the middle and bourgeois class of the country.
His goverment was plagued with corruption, drug trafficking, and incompetent people.
He intimidated Port-au-Prince with his chimeres and gangs and failed to move the country foreward.
He still have a naive illiterate mass that believe in him and may use their thrust to get back into politics and destabilize the country.
We don't need that now and should postpone his home coming to 20 or 25 years from now. Hopefully, Haiti, by then, will have a stronger democracy and a better economy.
