I thijnk you should just go with Envy, as chemical envy is kind of dumb no offense, and the chemical grills could have a deeper meaning going with and beyond Envy. Envy ius one of the 7 deadly sins, but everyone has Envy at one point or another, and Chemicals are deadly (or are at least synonymous with death) so that would all coincide. I dotn know, that is just my opinion, it's your case, so you can do whatever you want with it. Subolism is quite cool.
