why would h2s have a smaller bond angle (93.38) than scl2 (97.90)?

H2s are two H atoms attached as in H-H. If that is what you mean, it has no bond angle (actually, it has one but it is 180 degrees as in a linear angle.)
it is due to the loan pairs in chlorine atoms,they repell fom each other so that bond angle increaces
