I have played evil characters before in CRPGS but sadly it is rarely satisfying or believable. I hope BG3 will change this, I am really looking forward playing as the Dark Urge, starting out as someone who tries to hold back at first but then completely loses it and begins to revel in it. One of the few games where I enjoyed playing an absolute asshole, to the point that it became my canon playthrough was Dragon Age Origins. I played an ambitious elf mage who made pacts with demons, used his companions as stepping stones and always picked the side of those that offered him better rewards or power. Ended up chosing the dark ritual ending with Morrigan (who REALLY loved my asshole mage lmao), killed Leliana, had Alistair executed and Logain as my ally.
Too bad Dragon Age as a series went to shit right after Origins and none of that had any real consequences in the crappy games that followed
This said, in regular playthroughs (and by that I mean those in which I am not roleplaying a horrible person) I tend to adapt my moral choices to the situation. Some characters just DESERVE to met a gruesome end and I can see even an otherwise good aligned character becoming really cruel under specific circumstances. So, having the option to be evil is always a good thing in my book because you can use it to spice up a goody-two-shoes playthrough.
