After Killing Damien Darhk In Season 4 Finale, Will Oliver Kill Again In This Season Of "Arrow?"

It can be recalled that during the first season of "Arrow," Olive was hell-bent on killing everyone from the list that his father gave him. After spending five years on the island, making his way to survive, he definitely had a lot of blood in his hands. However, he's had a change of heart during the three succeeding seasons after his best friend, Tommy was killed during the season one finale.

After three years of trying his best not to kill anyone, he finally did during the season four finale when he killed the major villain in the series, Damien Darhk. Thus, executive producer Guggenheim revealed that they may play along with the darker side of Oliver once more in the upcoming season. Although he will be seen trying his best to put off the side of him that wants to kill, he may have another encounter that will prompt him to do so.

He has been trying to balance his killer instincts in the new season and even though it is going to be a struggle, he will try to find a way through it. The ultimate villain of the season that was from Oliver's past was finally introduced during the premiere, Prometheus. More of him and his former encounter with the "Arrow" will be tackled as the season progresses.
