> Penicillin works by killing other similar things

Pencillin is an antibiotic derived from fungi (Penicillium spp.). It kills bacteria. Bacteria and fungi are in two different kingdoms on the tree of life. These two groups of organisms are just about as dissimilar from each other as any two living things can be.

Other than they cohabit the same environments, hence why evolution/adaption has favoured the one that produces more bacteria toxin.

They live in the same environments and compete with each other for the same resources. Depending on your point of view, this is enough to make them more similar to each other than, say, lions and whales, which are both mammals.

Taxonomic closeness is only one kind of similarity.
