although i did make this as a self indulgent thing because of something ive kinda jokingly call myself the colors/imagery do have meanings.
various shades of purple represents the various levels of evil one can be, red is most representative in the emotions that motivate nefarious actions (anger and disgust being especially notable candidates for this), lime is representative of toxicity and boldness. Theres also a connection between disney villains and lime green as far as i'm aware.
i think horns, especially on humanoids, are usually associated with the dastardly due to various depictions of "demonic" characters having horns in Abrahamic religion. it also looks cool. The small drip on the bottom red stripe is representative of bloodshed, sure, but it also represents how ones nefarious demeanor can easily impact others and 'drip' into others heads, be it through corruption or bringing down their spirits yk.
