Unpopular Opinion, but Retaliation Does NOT Equal Instigation

We've all seen the posts where people are upset about getting banned for reacting to trolls. And I get it, toxicity is a bad thing and should be avoided. But let's break this down for a second.

Unless you're crossing a line, such as by using hate speech, retaliation for instigatory behaviour should not be punishable. What this teaches is that:

1. If you fight back against somebody who is mistreating you, you are at fault for not simply sitting and taking it.

2. If you antagonise somebody hard enough and often enough, you can take them down with you if you get punished.

This is a deeply flawed system and although the learning algorithm for League is good at picking up toxicity, it cannot distinguish between the person who inflamed the argument and the person who is reacting.

Trolls don't care about going down. They simply don't. It means they win, and if dedicated enough they will certainly make another account to do it again and again ad infinitum.

On the other hand, a player who is penalized simply for reacting to being baited will likely leave the game forever.

Consider the following situation: a young person, say about 25, is mugged. They are an upstanding person with no record. Their mugger is a repeat offender who has been imprisoned for petty theft and assault multiple times.

Under the current system in use by Riot? Both the mugger and the victim are jailed. The mugger doesn't lose much aside from their pocket change. The victim, however, has had their life and livelihood ruined. They now have a criminal record and can't apply for most jobs.

Does this sound like justice served? Does this sound like an effective system that protects victims and can't be abused by lawbreakers?

We need a more intuitive and nuanced solution than this.

EDIT: Since people are missing the point, I'll clarify it. I am not advocating, nor am I glorifying, toxicity. I haven't received a single reprimand from Riot in the almost 4 years I've been playing. But as long as the punishment system sides with the aggressor (first flamer/inter/AFK/troll) over the victim (unlucky recipient who flames back), then the punishment system is unequivocally flawed.
