THE worst: PISCES.
Looks like many other here named them, too, and I‘m not surprised.
They‘re wishy-washy, jealous, and pathetic because they get nothing done in life, then are constantly envious of others. They are spineless.
Capricorns on the other hand are selfish snd ruthless. They only ever really use people. If you can‘t be „useful“ to them in some way, they won‘t bother with you.
Geminis can be backstabby and can drop people randomly if they get bored or restless.
