> In hindu mythology, Raghavan (also Ravana [1]), who was blessed by gods and turned into villain by abducting Sita from lord Ram.

WTH :D

Raghavan != Ravana

(Only relation is that they were on the opposite sides and that made pretty much the whole epic Ramayana)

Raghavan comes from "Raghu" (another name for Ram). Raghavan kinda means "from Raghu" or so like "His descendants" or so.

AFAIK
