I do not believe in right and wrong in any objective sense, no. I believe in them as referential constructs thought into "existence" by whatever being has the perspective to assess benefit or detriment to itself or other things it may care about. Humans, for example, are such a being. "Right" or "good" end up being related to things, actions or motivations that lead to help or benefit to humans. And "Wrong" or "bad" end up being those things related to things, actions or motivations that lead to hurt or are detriment to humans.
As an example - a primitive mind may view mosquitos as "evil," or say something goofy like, "bad people get reincarnated as bad things - like mosquitos" (this being an actual, real-life example of something I have literally had someone say to me). From the perspective of humans, specifically, mosquitos are a nuisance, and can spread disease - potentially even life-threatening disease, and so they are "bad" from our perspective - which may be interpreted as "evil" by someone prone to readily accepting symbolism and stereotyping as "reality." But taking a step back, what do you think the mosquito thinks of itself (if it does so at all)? What do you think bats or frogs think of mosquitos? Are they "evil" from the perspective of those other animals that may rely on them for food? Probably not. If mosquitos were objectively "bad," then all things, regardless of their dispositions or perspective, would need to recognize them as such. It is only a very sophomoric, immature mind that can label mosquitos as "bad" all around, or, as a believer, ask questions like "Why did God create mosquitos?" as a reference to God creating something "evil." (also something I have heard from a real-life person).
However, while I do not recognize anything as universally "evil" or "good", "right" or "wrong," I do, easily understand what is beneficial or detrimental to myself or my fellow human beings, and I do tend to use the colloquially accepted terms of "right" or "wrong" to convey when I feel something is on one side of the benefit/detriment line or the other, and to simultaneously convey my stance on that subject (whether I, as a human, do or do not find various action/motivation acceptable from my fellow sentient beings).
But no... nothing is objectively "evil." Even something like "murder" can be seen as a benefit from another being's perspective. For example, a house-fly. Let's say a person is doing dishes, and a housefly is intent on getting at the food stuck to the plates, but that human doing the dishes just keeps swatting at the fly. If someone were to walk up and murder that human being, that would then allow the fly to either go after the food on the plates, or instead dine on and lay eggs in the dead human body that was also just provided to it by happenstance. The murder was of benefit to the fly, in other words, because a fly would likely always rather see a dead human being than a live one. This is not the fault of the fly, nor does it make the fly "evil" by any stretch of the imagination. His goals are just completely different from ours, and therefore what is "good" or "evil" from the fly's perspective will be entirely different from our own.
