How to balance aggression with going light

So during a few sparring rounds today I turned up the aggression and found a lot of success with landing shots. However this was unfortunately due to bad intent. Other partners were going hard, my ego doesn't make me beat up other people, instead it stops me from saying "you're going too hard" in drills and sparring. This has led to a mangled leg because I refused to say anything during leg kick drills. I'm working on this still, I'll fix my ego eventually.

Anyways, ya, people were going hard so I decided to match them. I discovered that I almost always pulled my punches, this didn't just reduce my power but also my reach. I also avoided hitting my sparring partner when they were wide open cause like, they probably know what would be coming so why hit them right? The following rounds I landed way more crosses which made me pretty happy (cross is my favourite punch) because I committed to my combos more. Usually I can commit to offense without going hard when the tempo is slow, but if we're going fast I get anxious and hit hard. During a round I hit a guy 3 times he tripped and fell but at the time I was like "shit did I just drop a guy? The fuck is wrong with me". However he made it clear that he just tripped. I only ramped up my aggression cause of him but I still felt bad.

Another guy I sparred I did very well against him cause same thing, he was going hard so I became more aggressive and yah, landed a lot of shots on him. Next round he asked to go light, hit just as hard which kind of passed me off, so same thing happened. But again, this is not the way to spar and I feel horrible.

One time I threw two punches after the buzzer rang cause I just had tunnel vision and I decided to take a break from muay thai. No more punching after the buzzer but same tunnel vision sometimes. I'm usually reserved and unwilling to commit to any punches but I feel I'm hindering my growth here, but if I become more aggressive and commit to my punches more I get tunnel vision and become an asshole. What do I do?
