Sure.
Solomon Grundy was conceived as an enemy to the original Green Lantern, Alan Scott, and you could arguably call him Alan Scott's arch-enemy. Since Alan Scott's powers were weaponized from the green, his weakness was wood, or any plant-matter. Grundy was a monster composed of swamp matter, rotten wood and leaves on the corpse of Cyrus Gold, and was therefore immune to the ring's powers.
He was part of the scifi-horror villains that Alfred Bester brought to the magazine, like Vandal Savage. The two biggest influences on the character are Frankenstein, arguably the primordial example of the sci-fi superman and the tragic monster, and Edward Hyde, a forerunner to all dual personality stories and a dissertation on the nature of evil, society, shame, and repression, on a society thriving with those very aspects. Two characters who, besides having a vast influence on villains in general, also tremendously influenced the superhero genre as we know it.
The Frankenstein influence is more obvious, but it's the Hyde influence that interests me more in the character.
You can interpret Grundy as a stand-in for darker and unpleasant aspects of human nature. He is outright described as a "distortion of nature" by the hero who weaponizes natural energy, and numerous appearences of the character focus on Grundy's human traits, usually when he isn't written as being only able to recite nursery rhymes, as well as his sympathetic traits.
Likewise, several of Grundy's origins place him as a dark and malevolent force in opposition to Alan's. Gardner Fox wrote him as the result of natural phenomena (radioactive swamp water), Alan Moore positioned him as a failed Swamp Thing. James Robinson's Earth 2 proposed Grundy as an agent of a force known as The Gray, specifically to counteract Alan Scott's Green. And so on.
You could interpret Grundy as a Mr. Hyde for the common man, a monster who rises from literal nothingness, to become part of a mob, to then become it's accidental leader, and then lead a campaign of terror across the city even before he starts getting the taste for murder. A revolving, walking contradiction born out of death and conceived in filth, exploited and manipulated by his masters, fighting champions of the American Dream. Other stories that depict Cyrus Gold as a rich man and have him attack large monuments reinforce this aspect.
You can also interpret Grundy not just as a victim of sickness, but the sickness itself, an ugly blot on a better world that, even without evil intentions, can only destroy and corrupt all around it. Like Hyde, a primal and unending evil. As seen when Alan Scott himself became Grundy in Showcase #55 or in Brightest Day, Blackest Night when Grundy's multiple origins serve only to place him as a walking archetype of decay and villainy whose origins don't particularly matter but whose hatred and strength are in active opposition to his hero's kindness.
Or you could just see Grundy as a huge zombie monster with nothing else to him. Whatever works.
Either way, I really like Solomon Grundy and I think writers do the character a huge disservice by reducing him to only being able to repeat his nursery rhyme and just drawing him as a Hulk clone.
