Why do people defend intentional feeders?

Well, i really dont see the point. So to start, i get if its your permade, ofc its still against the rules to int, but lets say he tilts, starts inting, and out of good friendship, you defend him, but this being random people willingly defending intentional feeding. Inting since season 2 - 3 is i belive the biggest problem in entire lol community, sure, toxic, afking, etc, but all of those gives little to none advantage to enemy team, while someone, who gives enemy 10/0 in 6 minutes is basically deciding who the winnner is, due to the fact that at 15 min, the teamfights are unbalanced, one team has 20 more kills and thus, more items. Sure, winnable, but harder, much and unnecesarily. So for example im gonna use a game i had a sec ago, where both me and bot went 3/0 in early game, looked free, then our mid out of nowhere started inting, running into 5 enemyes unstopping, trolling, etc, basically Tyler1ing. Normal stuff, here is the part that bamboozles me. So after like 10 minutes of gameplay, one of us writes please report orianna for inting. To what he gets response "report you for toxic %%%". And from that point, whole enemy team started defending the still inting ori. I dunno if they just enjoyed that she wasnt on their team, or if this was some kind of new thing, but why would people watch someone int, and then defend him, and gang up on someone who politely asked ONCE to report the person ruining the game and violating the summoners code.... at the end 4 of our teamates reported the ori, but im the end chat 2 or 3 enemyes actually honnored her, and reported all of us for unsport beh, still defending the ori, basically false reporting and defending a person violating the Sum Cod. I mean ok, maybe its considered rude to ask for a report, but asking for one report ONCE compared to inting for 30 minutes... i mean common, thats some next gen phoenix wright justice system. Forums are full of "WHY WONT RIOT TAKE CARE OF INTERS" posts, well. here you go people, this is why. Because people support them and defend them during the act
