Why did Rey kiss Ben?
Because he died happy. He returned to light when he wasn't sure if it was possible he could - and he was able to give the girl he wanted to love his life (force). She in return was able to gave him a kiss, because she could finally accept him. Ultimately it was more than he was expecting.
