Never underestimate someone who’s been through significant pain. Pain offers perspective, and those who have been through it, more times than not, are willing to fight with everything they have, relentlessly. Those who have experienced it tend to see life through a different light, they tend to fight more aggressively. You can sense an individuals pain. You can sense the calm before the storm when they set their sights on something. They walk with pain. They function with pain. An individual who has been kicked, beat down, and scarred in the past might never forget it, but that is not a bad thing. Pain can be used as a tool for achieving what that individual might be after. Pain should never be underestimated.
