Spoilers can work 1 of 2 ways, depending on how you look at it; It can either ruin the story for you (which people generally think is the defacto answer when anyone states a spoiler) OR it can enhance the story for you, it can give you a better understanding of whats happening than if you read it the first time and miss things out because you weren't paying microscopic analytical attention to each sentence.

Before i read the LNs for DxD, I had read through so much of the wiki; from character pages to the relationship pages (mainly on the main characters surrounding Issei and the ORC) but it didn't ruin the story for me when i began reading the novels.

Just because you know something happened, doesn't mean you know why or how it happened. It also doesnt give you context on what happened before and/or after what ever the spoiler was.
