I have a suspicion that most deathcore bands don't actually take things seriously, they're just full of energy and happen to like deathcore - not necessarily depressed and evil people like some might believe. We Butter the Bread With Butter is a good example if you didn't already gather from their name alone. Originating in Lubben, Germany, We Butter the Bread with Butter combines traditional deathcore elements with melodic, electronic music characteristics. In fact, the band originally started with only two people as a joke, but gradually grew into a serious project and added enough members to make a full band. They now have several albums out, although mostly in German, there are a few Western gems like World of Warcraft and I shot the Sheriff.
Although this probably isn't exactly an entry-level deathcore band, if you find yourself intrigued by the undeniable irony, try listening to this song Der Kleine Vampir, which means "The Little Vampire" in German and is named after a series of popular children's books.
