The effects for the same trifling bad deed can also be differently experienced because of differences in the doer. Differences in his/her development, character, being limited, big hearted, or not etc. The sutta explains.
I think it is good to note that it concerns trifling bad deeds. But still some can go to hell and another person nearly experiences any ripening effect, with the same trifling deed!
