Governor Perry claimed that he was aware that there were serious problems with the forensic evidence presented to the jury but he was so impressed by the testimony of a "jail-yard snitch" that he was still convinced that the jury "got it right". Apparently, the claim was made that the the "jail-yard snitch" received no "benefit" from his testimony. Turns out that the snitch was well rewarded for his testimony (see link below).
A certain number of innocent defendants are convicted. No Criminal Justice System is perfect. If a convict is later exonerated, he can be released. If he has already been executed, its more of a problem. Particularly for the governor who signed the death warrant. The problem with Death Penalty type cases is that they are generally particularly heinous. There is no worse crime that I can think of than killing your kids because you don't want the responsibility of caring for them. There must have been pressure on the DA to get a DP conviction and he may have been "certain" of Willingham's guilt. It must be frustrating in situations like that where the evidence just isn't there. I can see why the DA "crossed the line" and why the Governor backed him up in spite serious problems with the trial, but they are inexcusable. They violated the oaths of their offices and probably put an innocent man to death.
