The character of Becker in the film "M" had many childlike qualities, which drew in his victims. These qualities that Becker possessed, he exploited to his own gain. The children immediately gave him their trust because of his ability to relate to them, and he knew that. But I really don't think this was really an alter ego, because he seemed to have these traits all the time. Inside he was really a sick man, to kill there has to be something wrong with him, epically to kill small children, and furthermore little girls.Becker knew how to dram them in. He bought them balloons, and whistled. He bought them fruit, and candy, and openly ate on the street with them. Something that was, "against the norm", for grownups to do. He chatted them up, and they even felt comfortable enough to call him uncle. Becker when confronted reverted back to childhood, acting like he didn't know right from wrong.

In the case of John Wayne Gasey, he preformed as a clown and acted like a perfectly nice gentleman when luring his victims.

If no one trusted his, the war wouldn't have been as devastating and the jews would have left Germany far before they were ever marked as pariahs.Becker had to be trusted or his ploys would have never been c...
