People preys on the weak because it fears the strong.
I think the strong is good, the weak is bad. It might be a too extreme opinion, so I will add my comment.
I say that people harass others not because they are 'evil' but it is their innate 'instinct' to harass or exploit weak people.
The reason for that I assume is from the fact that bullying specific weak classmates in childhood is very common in global and any kids don't have serious guilty for their deed. Even though bullying directly weak classmates are only a few (who're bold and brave), any others (who don't want to be involved in) also don't like to hang out with victims, even just mock them or enjoy the show behind. It's not much different even in our adult society.
So humanity was born like that I assume. Also, I don't want to say that's evil. It's just their natural instinct like animals. All humans have this instinct to harass or exploit the weak inside but they get education morality which suppresses this desire as they're grown, or they don't do that because of others or society's eyes. (I say even people who are considered 'good' can harass weak people. But this is not the directive but subtle way. I've seen many 'good' people act like that in my life. Hypocrisy itself.)
Now let me have one extreme example.
Some woman was raped by gangs. Of course, she will blame gangs. But I want to ask her. "Did you try to protect yourself by recognizing that you were born as a woman who is weak physically? Learning Jiu-jitsu is fine, having lethal spray is fine. Both are better. Did you try even a little?"
If she didn't proceed to protect her even for a little bit, I don't think gangs who raped her has 100% responsibility. If a woman is strong and smart in the will, she will prepare to protect herself as knowing this world is very harsh and dangerous. There are already too many successful cases that a woman could save herself by using special weapons (spray) against sexual assault or rape.
Everybody knows that sexual crime is very prevalent and common today.
So if a woman didn't prepare anything to protect herself, I think she also helped to finish this kind of crime. Thus, I don't pity her at all.
Someone may get the point.
I don't say that I worship the strong itself, but people must become strong for preventing this kind of harassment from others.
Someone will object. "If you say that, you can be also bad for someone who is stronger than you."
Then I will answer. "I agree that I have some possibility to cause harassment or crime from someone who is stronger than me because I am weaker than them. But if I am a little weaker than them, will they really try to harass me? What if they also can get hurt a little by me? Then they will skip me, and seek other stupid, easy target comparatively than me. And as a result, the weakest or stupidest target becomes bad to bring crime or harassment. (Don't get me wrong, here strength doesn't mean only simple wealth or power but also somewhat wisdom and smartness.)
When all people can protect themselves with enough power, there will be no trouble or crime, and peace can come. Even though this peace is not real, I don't think there is no true peace in the world at all. "If you want peace, prepare for war." That's what I want to say as "Peace by equality of each power." I know, of course, it will never happen in reality. It's just my theory.
*** Therefore, I can't say that some victims who can't do anything to protect themselves because of a specific environment which makes it impossible is samely bad. ***
The important fact is not that the strength itself is good, but trying to become stronger for protecting self and preventing harassment or crime from others is. Maybe somewhat intention or will to be stronger.
That's why I want to avoid or contempt weak or stupid people who blame only others but not themselves. NEVER. They never consider that their weakness might bring this all problems. Don't you think this mind is childish and selfish a little bit?
I'm sick of those people srsly.
