The redarkening of DC is not "Marvelizing" DC. DC was dark in the beginning before Marvel. DC was lightened because DC editor Whitney Ellsworth created a Code of Conduct Editorial Board in 1941 which included a ban against all killings and excessive violence. The editorial policy was to get away from Batman and other characters vigilantism and to bring them over to the side of the law and make them all as wholesome and tame as possible. It was intended to protect DC from the growing criticisms of comic books in the 1940s and 1950s by Sterling North, Fredric Wertham, Greshon Legman, and the U.S. Senate which lead to the 1954 Comics Code Authority forcing E.C., Gleason, Fox, Fiction House and Quality out of business. Long before Marv Wolfman's New Teen Titans in the 1980s, the redarkening of DC really began with Denny O'Neil, Neal Adams, Elliot S. Maggin, Len Wein, Bernie Wrightson, Michael Fleisher, Jim Aparo and Marshall Rogers taking a stand against the censorship Code and liberating DC in the 1970s with dark and gritty groundbreaking material. This all paved the way for Marv Wolfman, Frank Miller and Alan Moore.
