I built this circuit (with transistor \$\beta = 100\$) and my result (when simulating with Falstad) is 2.582 mA through AM1 and 258.206 mA through AM2 (towards the negative side of the battery), in particular, even more current leaves the collector (in the wrong direction) than the emitter. The results are somewhat different when simulating with CircuitLab.

Why doesn't the transistor block current from the base to the collector? It this not what a transistor should do? How can I prevent this behaviour?
