But could Cloud forgive this?

"I managed the team rebuilding Nibelheim. I didn't know what happened at the time. Sephiroth and Zack had passed away, the city burned. Shinra was concerned and said that they had the people living in a temporary shelter nearby. That they were going to help rebuild. That many people were too injured to discuss things, so my team and I did our best to rebuild quickly. We were brought in by helicopter, so I couldn't see that there wasn't survivors. We built the shells of the homes. After that..."

Well, after that someone else took over.
