If nature kills the weak then how come animals like sloths still exist? They are slow as fuck and can die from eating a little more than usual (their bodies spend so much energy for digestion that they collapse and die).
And how come stray cats roam the streets if they cant even cross the street properly (cats are basically blind).

You guys gotta understand: God protects these animals because He loves them. Its God who decides which species die and which continue. Darwin is fake and gay.
