A lesson we can take from Sisera (that you probably never heard it Yeshiva).
If you analyze it, it would appear that Sisera was a sex addict. Thus, when the women were comforting the mother of Sisera as to why her son was late, they told her don't worry, "רַחַם רַחֲמָתַיִם לְרֹאשׁ גֶּבֶר". Rashi explains this to mean, "don't worry, he's late because he and his officers each have 2 or 3 of beautiful Jewish women in their beds whom they are raping."
If that was the norm for this battle, then it was no doubt the norm for any battle. This is besides the fact that Sisera, no doubt, was a much-sought man. He was a powerful general. I'm sure he could have had all the woman he wanted. He hardly needed to be taking women by force. But then, when you look at what actually happened: he brings this massive army to crush Bnei Yisroel; lo and behold, his entire army gets wiped out (something that probably never happened to him before); he manages to escape and is on the run. One would think that the top priority in this situation would be his life, to get back to Chatzor where he came from as soon as possible. But on the way, he meets Yael. What does he do? According to most meforshim, he has sex with her. Now, he knows they are chasing after him. After all, he told Yael, if they come by looking for me וַיֹּאמֶר אֵלֶיהָ עֲמֹד פֶּתַח הָאֹהֶל וְהָיָה אִם-אִישׁ יָבֹא וּשְׁאֵלֵךְ וְאָמַר הֲיֵשׁ-פֹּה אִישׁ וְאָמַרְתְּ אָיִן.
You see from here what the addict brain can do to you. Your life can be on the line but an opportunity to have sex and it all goes out the window.
Thank you, Hashem, for helping me find GYE so I could get help now before it was too late.
