Kefka may have poisoned Doma, but there is no real emotional attachment to the place. There is only the one scene in the Forest with the train where you feel Cyan's misery. It is more kind of like: Kefka poisons castle. Cyan becomes angry challenges him. Party helps Cyan. Cyan joins party.
Whereas Sephiroth's destruction of Nibelheim occurs after you make an attachment with the characters (as you will have played with them). The flashback also creates attachments to Cloud's mum (for example). So when Sephiroth burns it down and almost kills Tifa, it has a greater emotional impact.
