Don't get over excited… the logic behind his actions is rather simple really.... follow the steps:

1- Man see region/world being run with the law of jungle…
2- Man see society being run with the mentality of "every man fins for himself"…
3- Man see woman…
4- Man see self a little horny...
5- Man see in rearview mirror no one watching…
6- Man see helping himself to a serving of you…

See? I told you it's purely logical… just think about it.. he only did as he saw fit.
