Evil in DnD

What exactly counts as evil in DnD? How evil does the character has to be to have an Evil alignment? I often hear it being discribed as being selfish - but how selfish do you need to be? What is exactly the threshold?
WARNING this is not a discussion about real life morality or alignments in general, but a very specific question that relates only to dnd and it's alignment mechanic.

Generally speaking if you fuck over others for your own gain (or nobody's gain) or cause needless suffering, you're evil.

Fulfill your needs and pleasure at the expense of others without any guilt or beneficial motives.

Evil is in theory about screwing others over to get what you want so I'd guess it's about majorly destroying lives to get what you want.

D&D is shit for this by the way, it doesn't help that one of their main PC classes is normally defaulted to Chaotic Good but by any internal logic should nearly always be Evil.

So, somewhere between the shit Rogues are allowed to do for some reason and the worst human being ever.

Evil in dnd is about exploting others for personal gain.

Needless suffering sounds like a good marker. I guess that relates to both people who enjoy making others suffers and those who simply truly do not care.
Fucking over others sounds a bit more flimsy tho, feels like it includes too much people
Thanks though, it makes it clearer

>the shit Rogues are allowed to do for some reason
Rogues can locate and defeat traps and locks, that doesn't make them evil or even malicious, unless that rogue chooses to use their skills to rob from needy.
Robin Hood is held as a CG icon precisely because he robbed from robbers and did not keep the gains for himself.
>What exactly counts as evil in DnD?
The game defines it fairly well in the book itself.
Do not take word twisting and hand wringing you see on Veeky Forums as anything other than people trying to subvert something that is actually pretty simple in order to say they are intelligent.
>How evil does the character has to be to have an Evil alignment?
Acts must be habitual or of such grandiosity as to afford it.

using necromancy

Actually no, soul fuckery is evil, and habitually releasing undead from your control is also evil. Necromancy in its self isn't. There are very few spells that are inherently evil, and all of them involve some manner of soul fuckery, irreparable damage, or inflict prolonged agony in the process of killing.

Oh come on, you can use the Rogue class perfectly benevolently but you know as well as I that most PC Rogues should by any rights be Evil. Honestly I suspect most PCs should be Evil, almost by default they're choosing a life of killing sentient creatures for their money.
